摘要
在研究了三峡库区秭归县八字门滑坡的工程地质条件及滑坡体基本特征的基础上,介绍了该滑坡的结构及变形特征,从滑坡形成条件和诱发变形因素两方面分析了滑坡形成的原因及诱发坡体失稳的主要因素.在不同工况下及地震作用下对滑坡体进行稳定性计算,结果表明,在库水位变化和暴雨情况下滑坡处于不稳定状态,极有可能复活.
Based on the studyies of engineering geological conditions and basic properties of the Bazimen landslide of typical accumulation horizon, this paper describes the characteristics of structure and deformation of the Bazimen landslide and analyzes main induced factors of the landslide. Considering the different water levels of the Three Gorges Reservoir, the stability of the landslide is calculated. The re- sults prove that the Bazimen landslide is unstable under the influences of rain-storm and reservoir im- poundment.
