摘要
降雨诱发边坡失稳破坏是一个复杂的地质运动过程,其破坏机理研究一直是热点和难点。该文从降雨入渗特性、边坡稳定性分析、降雨诱发滑坡的稳定性分析与试验研究出发,阐述了近年来强降雨诱发土质边坡破坏机理的研究现状,揭示了降雨条件下土体的入渗规律及诱发滑坡的失稳机理,对于工程上防灾减灾具有一定的实用价值,同时也为下一步研究滑坡灾害风险评估及其防灾减灾技术提供基础。
The rainfall-induced instability of slope is a complex geological movement.The research status of the failure mechanism of soil slope induced by rainfall is expounded in this paper according to the characteristics of rainfall infiltration,the stability analysis of slope,the stability analysis and experimental research of rainfall-induced landslide.And the laws of soil infiltration and the instability mechanisms of rainfall-induced landslide are revealed.It is a great practical value for disaster prevention and mitigation in engineering,and also provides the basis for the next researching on landslide risk assessment and disaster prevention and mitigation technology.
