摘　　要：重点介绍国土资源部“长江三峡地质灾害监测与预报”2000年科技专项计划中雨水及库水作用下滑坡模型试验研究成果。建立了室内人工降雨控制系统、水库水位控制系统、大型滑坡试验平台起降控制系统等和多物理量测试系统、非接触位移量测试系统、γ射线透射法水分测试系统等测试系统。以石榴树包滑坡为例,研究了水库型滑坡变形破坏规律。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 γ -ray water content measurement system,were set up.Taking the Shiliushubao Landslide as an example,the deformation characters of reservoir-triggered landslide are studied.
