Treatment method and application of scaling side slope landslide in phyllite rock area

Abstract

The invention discloses a treatment method of scaling side slope landslide in a phyllite rock area. The method comprises the following steps that a, on-site surveying and mapping of a landslide body slope length L, a slope alpha of the landslide body, an upper side area Au of the landslide body and the slope beta of the upper side surface of the landslide body are conducted; b, the risk of the slope landslide of the artificial scaling side slope of the phyllite rock area is calculated; c, the dangerousness grades are divided; d, the critical value Tcr of the treated terrain factor is set to be2.10, and if the treated terrain factor T' is less than or equal to 2.10, the treatment is qualified; if L is larger than or equal to 3m, and T' is larger than 2.10, the comprehensive treatment is continued. According to the invention, the terrain influence factors of slope landslide are comprehensively considered, the water gathering area at the upper part of the landslide body is reduced as a first treatment measure, the area of the water gathering area on the upper side of the landslide body is reduced, water gathering and water inflow seepage can be reduced, the slope of the landslide body can be reduced, the landslide power is reduced, so that the requirement for treating the landslide can be met, and the landslide prevention and control effect is improved.

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.
