Taking Baishuigou landslide, which isthesub-landslide(次级滑坡) of Tianjiapingpaleo-landslide(古滑坡)located inthenew Badong County,as an example,based on the engineeringgeologicalinvestigationresultsand anti-slidepiledesigndata ,the2Dfinite element modelwas developed and therati
32、onalcalculationparametersof the rock and soil and pile were chosen. According to thesimulation scheme, with ANSYS software, with pile and without pile, thelandslide stabilityunder water level fluctuation, considering gravityonlyand gravity and storm, was simulatedand analyzedseparately.Basedon them,
33、 we analyzed the effects of anti-slide pile under water levelfluctuation and storm. The results show that: thedeformation andfailure mechanismof Baishuigou landslide is apull-type.
