Formation Mechanism and Stability Evaluation of Chenjiapo Landslide in Gaochuan County

Based on geological investigation,field tests and laboratory tests for Chenjiapo Landslide,the paper elaborated the basic characteristics of landslide,its formation mechanism and evolution.Moreover,the slide stability under different working conditions was calculated and evaluated by limit equilibrium method and numerical simulation.The results show that the landslide is in the steady state under the natural state,and its stability coefficient is 1.168;the landslide is in the less stable state under rainstorm state,and its stability coefficient is 1.05;the landslide is in the basically stable state under seismic loading with magnitude VIII,and its stability coefficients is 1.065.The result of stability coefficients obtained by limit equilibrium method and numerical simulation are mostly consistent.

Key words:Chenjiapo Landslide,Gaochuan County,landslide characteristics,formation mechanism,stability evaluation
