摘　　要：通过自主研制室内人工降雨系统与滑坡模型槽,进行砂土边坡降雨试验。采用数字图像采集设备直观的观察记录滑坡发生、发展过程,从细观角度观察边坡破坏形态,研究降雨型滑坡在启动和运动过程中,颗粒运动规律、土体细观组构的演化规律。Through the indoor model test of artificial rainfall induced landslide, at the foot of the slope landslide start setting microscopic observation area, using high magnification digital microscope to obtain soil in each stage of microscopic digital image and analyze developing trend of soil micro structure.The slope failure pattern was observed from mesoscopic point of view, and the evolution of the mechanism of particle movement and the microstructure of soil was studied.

关 键 词：降雨型滑坡 模型试验 细观机理
