摘要
通过对西南某水电站在地下洞室的开挖过程中揭示的一些特殊地质现象分析认为该区存在一个从外表上很难发现的老滑坡体,根据该滑坡结构及解体特征,分析其变形破坏模式,认为它是一暴雨促发的平推式滑坡,并对其在各种工况下的稳定性进行量化评价。
On basis of the analysis of those particular geologic phenomenon which is revealed by the excavation of a hydropower station underground cavity in the southwest, this paper suggested that there was an old landslide. This article analysed the deformation and failure mode of this landslide according to its structure and disintegration characteristics. This landslide is identified a translational landslide, and the quantification evaluation on the stability is made under different conditions.
