| Landslide is a kind of natural phenomenon, which refers to soil or rock mass on the slope affected by factors such as river erosion, groundwater activity, rainwater immersion, earthquake and artificial cutting slope, under the action of gravity, along a certain soft surface or weak The belt slides in a downwardly or downward direction, either wholly or in a dispersed manner.Movement of the rock (soil) body known as the body or slip body, not moving the underlying rock (soil) body known as the slide bed.Landslides often cause huge losses to industrial and agricultural production as well as people's lives and property, and some even devastating disaster. In our country, there is a lot of mountain countries. At present, it is very urgent to study and control the landslide, which has caused great loss to the national production.The main work of this paper:(1) Study on a large scale lapse type landslide in Linzhou city of Anyang, Through exploration, engineering geological mapping, drilling, trenching, in-situ test and laboratory soil test methods such as physical and mechanical natural state of sliding body and sliding zone soil and saturated parameters are determined. In this paper, the main characteristics and the stability of the landslide are analyzed, and the harm of the landslide is predicted.(2) By calculating the stability coefficient of the slope gravity, gravity and rainstorm, gravity and seismic conditions under three different conditions, obtained under gravity conditions of landslide is in a stable state, but in the two conditions of the slope stability safety coefficient is less than 1, the slope will decline.(3) Based on the technical and economic comparison of several treatment schemes, the control form of anti slide pile and surface water cut was proposed. Through checking calculation, to meet the requirements of slope stability. Through technical and economic comparison, the governance program is reliable and economic rational. |
