土工离心机技术在山区地质灾害研究中的应用

Application of Geotechnical Centrifuge Technology on Geological Hazards Research in Mountainous Areas

土工离心机是地质灾害模型实验研究中的重要装备,它通过高速旋转产生离心加速度模拟超重力环境。应用离心机进行山区地质灾害模型实验时,对模型缩尺比要求各不相同。总结了滑坡、降雨、泥石流模型实验的研究现状和实验缩尺比要求,归纳了国内外离心机技术的进展和未来发展方向。

Geotechnical centrifuge is an important equipment in the experimental study of geological disaster model.By rotating at high speed,it produces a centrifugal acceleration to simulates a hypergravity environment.When applying centrifuge to simulate the geological disaster experiment in mountainous area,the requirements of model scale ratio are different.It summarizes the research status and experimental scale ratio requirements of landslide,rainfall and debris flow model experiments.It also concludes the progress and future development direction of centrifuge technology at home and abroad.
