A control method and application of slope-cutting slope and landslide in phyllite area

Abstract

The invention discloses a treatment method for landslides on side slopes in phyllite areas, comprising the following steps: a. On-site surveying and mapping the slope length L of the landslide body, the slope α of the landslide body, and the upper side area A of the landslide body u and the side slope β on the landslide mass; b, calculate the risk of landslides in the artificial cut slope in the phyllite area; c, divide the risk level; d, set the critical value Tcr of the terrain factor after treatment to 2.10, if If the topographic factor T'≤2.10 after treatment, the treatment is qualified; if L≥3m, and T'>2.10, continue comprehensive treatment. The present invention comprehensively considers the terrain influencing factors of the slope landslide, takes reducing the water catchment area at the upper part of the landslide body as the preferred control measure, reduces the area of ​​the water catchment area at the upper side of the landslide body, reduces water catchment and water infiltration; and cooperates to reduce landslide body The slope can reduce the power of landslide, so as to meet the needs of landslide control and improve the effect of landslide prevention and control.

Description

technical field [0001] The invention relates to the field of prevention and control of artificial slope cutting and landslides, in particular to a control method and application of slope cutting and landslides in the phyllite area. Background technique [0002] The new slopes formed by artificial slope cutting are widely distributed in low mountain and hilly areas, especially in the eastern low mountain and hilly areas of our country. [0003] Due to the growth of people's income, the per capita living area has also been increasing. The original housing can no longer meet the growing living needs of local residents, and new buildings need to be built. But our country has less arable land, and to protect the arable land, if we want to build new houses, we have to find another way. The only way to consider is to form a new dwelling site by cutting slopes on the side of a low mountain. In order to reduce the construction cost, increasing the slope of the slope is the usual ch...

Problems solved by technology

[0008] The existing technologies represented by the above-mentioned patent documents are mainly aimed at soil landslides or rock landslides in red bed areas, and are not applicable in other areas, nor can they judge the landslide risk of artificially cut slopes, nor can they be used to guide artificial landslides. Management of Slope Cutting

[0009] In addition, these studies are only used for natural slopes, and the slopes of potential landslides are often below 45 degrees, and it is almost impossible to exceed 50 degrees.
