Abstract:The landslide model test results under the conditions of rainfall and reservoir water fluctuation from the ′2000 scientific specified plan of Monitoring and prediction of Geological Hazards of Three Gorges Region are introduced. The test systems,including indoor artificial rainfall control system,reservoir water level control system,control system of the large-scale rising and falling of experimental platform,and the measurement systems for multi-physical parameter measurement,non-contact optical displacement measurement,and g -ray water content measurement system,were set up. Taking the Shiliushubao Landslide as an example,the deformation characters of reservoir-triggered landslide are studied.
