Formation mechanism and stability analysis of No.3 Landslide in Dangkou Village JiangXi Province
In order to evaluate the stability of No.3 landslide in Dangkou village of Jiangxi Province accurately and clarify its deformation and failure law ulteriorly, the No.3 Landslide in Dangkou village is studied here with the help of theoretical analysis and FLAC3D numerical simulation. Based on the limit equilibrium theory and strength reduction theory, the stability of the landslide was analyzed qualitatively and quantitively with the help of numerical simulation firstly. The researche shows that the No.3 Dangkou village landslide is a kind of disaster type of landslide with debris flow coupling damage in early stage and later stage under the comprehensive influence of internal and external factors. It has characteristics of wide range, great damage, and strong local destructive force; under natural conditions, the landslide is in a stable state with only partial compressive failure occured on the superficial surface; under rainstorm conditions, the instability of the landslide increases obviously, on the whole the possibility of deep failure is great; in general, it belongs to traction landslide. The research results can provide technical reference for comprehensive landslide control and have certain theoretical and practical significance.
