滑坡体水岩作用机制与变形机理研究

Study on Rock-Water Interaction and Deformation Mechanism of Landslide

水岩作用对滑坡形成与发展具有非常重要的影响。从水岩作用的材料力学效应、水力学效应、化学效应及地震效应4个方面对某滑坡体的水岩作用机制进行了分析,其中前3种作用机制对滑坡体的变形演化与复活关系最为密切。在此基础上,对滑坡体变形机理进行了综合分析。分析认为,滑坡发育的基本条件有软硬相间的有利地层结构、地质构造条件等;滑坡发育的诱发因素有降雨、水库蓄水及人类活动等。

The rock-water interaction is a very important factor to the occurrence and development of landslide. This article analyzes rock-water interaction, including mechanics effect of materials, hydraulic effect, chemical effect and earthquake effect in a typical landslide, in which front three items are very relevant to the deformation and revival of the landslide. Then the article analyzes the deformation mechanism of the landslide. The basic conditions of landslide development are the stratum structure and the tectonic geology mainly, and the induced factors are the rainfall, impoundment, the activities of human being and so on.
