摘要
以石棉县双加坪滑坡为例,在探明滑坡地质条件的基础上,分析了滑坡形成的原因;基于极限平衡理论折线形滑动面条分法进行稳定性分析。结果表明:在天然状态下,滑坡基本稳定,在持续降雨条件下,大部分不稳定或欠稳定;在地震力作用下为不稳定滑移状态。对此,提出了合理的处治措施。
Based on the verified geological conditions of landslide,the contributing facto for landslide is analyzed by exampling the landslide of Shuangjiaping,Shimian,and stability analysis is performed in the broken line sliding surface slicing method based on limit equilibrium theory. The study results show that the landslide is in stable status under the normal condition,mostly unstable or under-stable status under the condition of continuous rainfall and unstable and sliding status under the condition of the earthquake force. A control measure is put forward in the paper.
