In the experiments, a high-density resistivity method is used to explore the electric structure of landslip mass, and a resistivity-changing anisotropy method is used to monitor the orientation and speed of main fracture extending of landslip mass. The results are as follows. 1 The exploring experiments have verified a part of creep deformation borderline, the depth and thickness of groundwater horizon, and the property of superstrata in the landslip mass investigated formerly, which have proved that the landslip belts contain rich groundwater; 2 The main fracture extending orientation inferred from the resistivity-changing anisotropy accords with the strike of fracture belt of landslip mass deduced from GPS displacement. Moreover, the changing rates of resistivity-changing anisotropy coefficient matches with the changing speeds of deep displacement of landslip mass were measured by suing clinometer in the borehole. 展开更多
