滑坡灾害重复治理前后的稳定性对比分析

向家坡滑坡是一个具有多层滑面的组合式滑坡,滑面由浅层滑面、中层滑面和深层滑面组成.针对该滑坡受到不良地质情况和大气降雨等因素的影响,经过3次治理后并未取得良好效果的情况,拟对该滑坡进行第4次治理.在密切监测滑坡滑移的情况下,采用ABAQUS非线性有限元程序对滑坡体前3次治理与第4次治理效果进行三维数值模拟计算对比分析,得出数值模拟结果与监测结果符合很好.

Stability Contrast of Landslide Disaster After Repeating Control

Xiang-jiapo landslide,which consists of shallow layer,middle layer and deep layer,is a multi-landslide with several layers.Influenced by geological condition and rainfall,it have not obtained good effect even after three-time control.Because the distortion of landslide increase so fast, the government planed to control the landslide for the forth time.Based on monitoring data of the landslide movement,the paper make a constrast analysis of 3D numerical simulation's calculating between the formal control and the forth time control by a non-linear finite elements programm ABAQUS.Both results of numerical simulation and monitoring indicate that the forth time control have achieved good effect.
