20091853 An Jinzhen(School of Earth and Space Sciences,Peking University,Beijing 100871,China);Zhou Pinggen Experiments on Exploring and Monitoring Landslip-Mass Using Geoelectric Resistivity Observations(Acta Seismologica Sinica,ISSN0253-3782,CN11-2021/P,30(3),2008,p.254-261,6 illus.,1 table,19 refs.)Key words:resistivity methods,landslidesIn 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 super strata in the landslip mass investigated formerly,which have proved that the landslip belts contain rich groundwater
