slope engineering
Slope engineering was an engineering field that involved many aspects. There was a book titled "Slope Engineering" published by different publishing houses. The content of the book would focus on problems such as slopes, landslides, dangerous rocks, collapses, mudflows, and bank collapses. In combination with relevant national standards and specifications, it would elaborate on the investigation, testing, analysis, evaluation, treatment, and monitoring of slope engineering. It will introduce in detail various slope engineering analysis and evaluation methods and slope engineering treatment measures. It will also give several main application programs for slope engineering analysis and evaluation. There are some problems in the classification rules of the safety level of slope engineering, such as unclear safety level, difficulty in classification, and intermittent changes. Although it is generally determined according to the relevant tables, the actual safety level is basically determined by the severity of the damage consequences (Level 1 when the damage consequences are very serious, Level 2 when it is serious, and Level 3 when it is not serious). There are contradictions between the current classification rules and the content of the table, and there is no corresponding relationship between the slope type and the severity of the engineering damage consequences, which will cause difficulties in the classification of the severity of the damage consequences and the safety level. There were relevant analysis and suggestions for these problems, such as adjusting the form of the safety level division table. From the perspective of the Slope Engineering Technology Conference, the 16th Slope Engineering Technology Conference was held in Beijing on October 21st. The conference was themed with "Safety and Protection of Engineering Slopes under Extreme Conditions", covering the development status and future of modern slope engineering technology, survey and evaluation technology, prevention and control technology, safety intelligent monitoring and early warning technology, ecological restoration theory and technology, new construction methods, new technologies, new equipment, digital and intelligent technology, etc. This reflected the trend of slope engineering towards green, safe, digital and other high-quality development. In terms of slope protection construction, the first step was to survey and set out, then set up a falsework, and then use a cannon machine to drill holes in the side slope (the position of the holes was required to be high, and the error of the hole distance was not more than 5 cm). After the acceptance was passed, an anchor rod made of several processed steel bars was placed, and then the cement mortar was poured into it. After the mortar solidified, the steel bar frame was built, and finally, the slope was afforested (using a grass spraying machine to scatter grass seeds). Through these layers of construction reinforcement, the firmness of the slope was guaranteed. Not enough TV dramas? Hurry up and click on the books below to read the wonderful original novel!
Safety classification of slope engineering
There are many factors to consider in the safety classification of slope engineering. Firstly, it was divided into three grades according to the seriousness of the possible damage consequences (endangering people's lives, causing economic losses, and causing adverse social impacts). It was determined by combining the type of slope and the height of the slope. Among them, very serious damage meant that it would cause heavy casualties or property losses; serious damage meant that it might cause casualties or property losses; and not serious damage meant that it might cause property losses. When the damage consequences are very serious or severe, the safety level of the slope engineering that meets the following conditions shall be classified as Class I: the slope engineering controlled by the extroverted weak structural plane, the slope engineering in the engineering landslide area, and the slope engineering with important buildings (structures) in the slope collapse area. In addition, each section of a slope project can adopt different safety levels according to the actual situation. For slope projects with extremely serious dangers and complex environmental and geological conditions, the safety level should be appropriately increased according to the project situation.

Slope and Foundation Pit Engineering
Slope and foundation pit engineering included many aspects. In terms of slope engineering, the artificial slope with a height of more than 8m (including 8m) and the natural slope that affects the safety or stability of the building (structure) or the slope with a complicated geological condition and surrounding environment although it is not more than 8m belong to the category of building slope. In terms of foundation pit engineering, the excavation depth is more than 5m (including 5m) under the natural ground or the foundation pit with a depth of less than 5m but complicated geological conditions and surrounding environment belong to the category of deep foundation pit. The project included slope and foundation pit support, underground water control, surface water diversion and drainage, earth excavation, foundation pit refill, environmental protection around the foundation pit, monitoring, etc. In terms of management, taking Henan Province as an example, the competent department of housing and urban construction was responsible for construction management, the quality and safety supervision agencies of construction projects at all levels were responsible for daily supervision and management, and an expert committee would be set up to review the design plans of the more dangerous slope and foundation pit projects. The construction unit shall contract out the project to qualified and experienced units according to law. It shall investigate the neighboring conditions and provide information before the survey. During the construction process, it shall ensure the safety and normal use of neighboring buildings (structures), roads, underground pipes, etc. From the perspective of technical specifications, there were specifications such as the General Code for Building and Municipal Foundation, and most of the provisions were principled. The implementation and operation aspects should rely on the recommended standards such as the Construction Foundation Pit Supporting Technique Code JGJ120 - 2012, the Construction Slope Engineering Technique Code GB50330 - 2013, and the Construction Foundation Pit Engineering Monitor Technique Standard GB50497 - 2019. In terms of slope construction, it included surveying and setting out, building a falsework, drilling holes, placing anchor rods, injecting, building a steel frame, and planting trees. In addition, in terms of earth pressure calculation, there were related theories such as Rankine's earth pressure theory and Coulomb's earth pressure theory to calculate the active earth pressure and other related parameters.

Judgment of Windward Slope and Leeward Slope of Sand Dunes
The windward slope of the sand dune was gentle, while the leeward slope was steep. The windward slope of a sand dune referred to the side of the sand dune facing the wind, which had a gentle slope, while the leeward slope referred to the side of the sand dune facing away from the wind, which had a steep slope. This form was formed by the wind and the accumulation of sand. According to [2] and [4] in the search results, the windward slope of a sand dune is a gentle slope, and the leeward slope is a steep slope. Therefore, the judgment of the windward slope and the leeward slope of the sand dune could be carried out according to the slope.
Slope Topographic Map
The topographic map of the slope was a map that reflected the terrain of the slope. In the topographic map of the side slope, according to the relevant national drawing standards, the leading end of the long and short lines of the side slope and the cone slope was the high end. Observing the long and short thin solid lines of the slope in the figure, the length of the ends is aligned with the leading end (i.e. the high end and the high end), and the other direction is the low end, which is the direction in which the slope slopes downward. At the same time, based on the baseline position in the road (highway) plan, it could be determined whether it was an excavation slope (cutting) or a fill slope (embankment). For example, if the length of the thin solid line at the end of a certain point is aligned and leads to the point, it means that the point is low and the direction of the lead is high. This side is the cutting slope; otherwise, it is the filling slope. In addition, the height of the terrain could also be judged according to the absolute elevation value marked on the ground. The terrain with a large value was high, and the terrain with a small value was low. This information would help engineers understand the height trend of the slope terrain, the type of slope, and so on. It was of great significance in slope construction, protection construction, monitoring, and so on. Not enough TV dramas? Hurry up and click on the books below to read the wonderful original novel!
Three Forms of Slope
The slopes can be divided into natural slopes and artificially excavated slopes according to their causes of formation; soil slopes and rock slopes according to the nature of stratum rock (soil); layered slopes, block-shaped slopes and net-shaped slopes according to the structure of rock stratum.

The North Slope of Changbai Mountain
The following is a detailed travel guide for the northern slope of Changbai Mountain: * * 1. Initial preparations ** 1. * * Entrance ticket reservation ** - Changbai Mountain Northern Scenic Area tickets: There is no need to buy tickets in the off-season, but if you go in December, it is recommended to buy more than seven days in advance. It was hard to get a ticket during the peak season. One could book a ticket a week in advance through the official small program "Changbai Mountain ticketing platform". The ticket price was 225 yuan, and the ticket to the main peak of the Heavenly Lake was 80 yuan, making a total of 305 yuan. University students and other preferential groups can pay attention to preferential policies. - The main peak Tianchi ticket: very popular. It may not be possible to book a ticket at the last minute. You must book it in advance. 2. * * Understand the weather **: Check the weather forecast in advance. If the weather is not good (such as snowy days), the scenic area may be closed. Choose a sunny day to go. 3. * * Carrying Items ** - Identity card (If it is a discounted ticket, you need to bring the relevant documents). - Clothes: You can wear quick-drying pants, warm pants, sweaters, down jackets, hiking shoes, gloves, hats, scarves, etc., and can also adjust according to the actual situation. You can rent cotton clothes, cotton pants, and cotton shoes on the mountain and down the mountain. - Food and water: There is less food on the North Slope Mountain. You can bring your own snacks and water. * * 2. Transportation ** 1. * * Arrived at the northern slope of Changbai Mountain ** - If you took the high-speed rail to Changbai Mountain, there were buses and taxis outside the next station. The bus was more cost-effective, and the taxi started at 80 yuan. You could also choose to take a bus to the North Slope of Changbai Mountain. - If you drive to the parking lot, the parking fee is 25 yuan (10 hours), and 20 yuan outside the scenic area. 2. * * Transportation within the scenic area ** - After entering the park, they took a bus. It took about an hour to reach the transfer point to the main peak of the Heavenly Lake. Here, he took out his ID card to check the ticket and changed to a seven-seater commercial vehicle. The journey on the winding mountain road took about 20 minutes to reach the main peak of Changbai Mountain. Then, he walked for another two to three minutes to reach the Tianchi Lake. - After checking in from the Heavenly Lake, he took a seven-seater commercial bus back to the Green Abyss Lake bus stop. After that, he took a bus to the Changbai Mountain Waterfall, the Little Heavenly Lake, and other scenic spots. To go to different scenic spots, he might need to change to the corresponding bus at the transfer center. * * 3. Tour Routes and Scenic Spots ** 1. * * Heavenly Lake ** - The opening hours were dependent on the weather and were not open every day. The 80 yuan in the ticket included the cost of taking an off-road vehicle from the transfer center to the main peak of Tianchi (round trip). The one-way journey was about 20 minutes. After arriving at the Heavenly Lake, it took about ten minutes to walk to the edge of the Heavenly Lake. The cold wind here was biting, so be careful to keep warm. There were many people taking photos at the Heavenly Lake. They had to seize the opportunity to take photos. 2. * * Hot spring, Changbai Waterfall (close enough to visit together)** - You can choose to take the boardwalk (about 20 minutes) or take a snowmobile. The scenery along the way was beautiful and suitable for taking photos, but one had to pay attention to the anti-slip. There were Changbai Mountain hot spring eggs for 10 yuan each, and drinks with the words "Changbai Mountain" printed on them. The Changbai Waterfall was the outlet of the Heavenly Lake and also the source of the Songhua River. 3. * * Green Abyss Pool ** - The waterfall of the Green Abyss Pool was relatively small, but it blended in with the white snow and the scenery was beautiful. There was a Blue View Fast Food buffet at the Green Abyss Lake bus stop. It cost 60 yuan per person, and there was also a noodle fried rice that cost 25 yuan. 4. * * Underground Forest ** - It was the scenic spot with the lowest elevation on the North Slope. It is recommended to walk 100 - 200 meters in the forest to experience the primeval forest before returning, because the return trip is more tiring. The photos here were very good. 5. * * Small Heavenly Lake (option)**: If you have already seen the Heavenly Lake, you may not go to the Small Heavenly Lake. The scenery is relatively ordinary, and sometimes it will freeze. * * IV. Lodging arrangement ** 1. If you were looking for cheap and affordable accommodation, you could stay in Erdaobaihe Town. The price was more than 100 yuan per night. It was close to the scenic area. It took five to six minutes by taxi and ten minutes by foot. 2. If you were looking for high-end accommodations, you could choose Crown or Blue View Hot Spring Hotel. The hotel offered free hot springs. * * 5. Restaurant recommendations ** You can try Northeast Iron Pot Stew, Grandma's Rice, Pig Cuisine, Chicken Stewed Mushroom, Korean Cuisine, etc. On North Slope, you can go to White Mountain Street to find food. There are many restaurants there. They could also eat at the Blue View Fast Food in the scenic area. * * 6. Tour schedule ** It would start to get dark at around 15:30 in Changbai Mountain. It was recommended to enter the park as soon as possible. It was better to leave at 8 or 9 in the morning to ensure that the scenic spots were completed before 15:00. * * 7. Other matters to note ** 1. It was not easy to hail a taxi in the North Slope Scenic Area, but it was easy to stop a taxi. Don't listen to the chauffeur and the hotel's recommendation of a private car. 2. There were many people in the scenic area who were selling protective gear and buying them on demand. However, they could consider renting gloves, which were good at keeping warm. Changbai's novel is equally exciting. Everyone is welcome to click and read it!
Where is the prototype of Sanbian slope?
The prototype of the Three Slopes was the northern part of Myanmar. In a broad sense, it included the Golden Triangle (the triangular area at the junction of Thailand, Myanmar, Laos, and Kokang in northern Myanmar). For example, its geographical location and social environment were similar to the northern part of Myanmar. It was an area where gambling and drugs were rampant and lacked legal systems. In The Past of the Border Waters, Sanpo was depicted as a dark and chaotic place, which was consistent with the many crimes such as electricity fraud and drugs that had been exposed in northern Myanmar in recent years. At the same time, the three slopes were also based on Xishuangbanna in Yunnan Province. The characteristics of Xishuangbanna, such as the caravan road and the ancient tea horse road, were integrated into the setting of the three slopes. Not enough TV dramas?
