摘要
在我国西南山区,滑坡已成为威胁人民生民财产安全的主要地质灾害之一。本文就某厚层堆积体滑坡的稳定性进行了分析,在现场调查和室内数值计算的基础上,弄清了滑坡失稳的影响因素,大量降雨是滑坡失稳的主要诱发因素,坡脚开挖进一步加剧了坡体失稳。滑坡在天然状态下较稳定,在暴雨工况下不稳定。
In southwest mountainous area of China,landslide has become a threat to people and property as one of main geologic disasters.The paper is studied on stability of a thick layer of accumulation landslide,on the spot investigation and laboratory based on numerical analysis,It is found out the influencing factors of landslide,abundant rainfall is the main induction factor of the landslide,further excavation at the toe of the slope is aggravated of losing stability of landslide.Landslide is stable under natural condition,unstable in storm conditions.
