Stability And Site Available For Evaluation Of The Zhulingou Landslide At Gulin County Sichuan Province

Zhulingou landslide is a typical soil landslide. The landslide is the overall stability, local buckling under heavy rain conditions. A larger number of houses on the landslide, affected by the landslide deformation part of the houses wall cracking, local dip, instability, and even collapsed; For the local villagers caused enormous economic loss.At home and abroad at this stage of the forming condition of landslide deformation damage mechanics model and evolution research more mature. Yet for stable slope to landslide building damage caused by the reasons in the process of conversion and corresponding prevention measures research rarely. In this paper, Zhulingou landslide at gulin county sichuan province as the research object, through the exploration, investigation visit, combining with laboratory experiments, Using numerical simulation and the method of limit equilibrium method of calculation and analysis on Zhulingou landslide. According to the calculation results of the corresponding preventive measures are put forward. In this paper, the main research results are as follows:(1) Induced landslides are analyzed internal and external factors, And analyzes the deformation and failure mechanism of landslide.(2) By limit equilibrium method to calculate and analyze the stability of the landslide. By using Geo-studio software to simulate the stress and strain caused by the rainfall infiltration during the initial landslide and the change of landslide stability coefficient.,and also calculated the stability of landslide at present stage.(3) On the in-depth analysis of the landslide surface cracks and damage the relationship between buildings. Calculation and analysis of building foundation in a wide variety of crack stability; And corresponding prevention measures are put forward.(4) After through the corresponding preventive measures. According to the results of stability calculation, consult the relevant specification, venue availability on construction of Zhulingou landslide is evaluated, Zhulingou landslide construction site for the secondary site(moderately complex site), construction site is against building aseismic for location, site category as class II. Suitable for the construction of a Class C building on the construction site.
