摘要
巴东库岸段主要出露中三叠统巴东组二段(T2b2)红层,为软岩、硬岩相间,遇水极易软化,常发育大量滑坡,且潜在不稳定滑坡较多,而三峡工程的建设必将诱发并导致巴东库岸段滑坡地质灾害的发生。分析了西壤坡西滑坡的特征、滑坡发生的机理,并进行了稳定性计算,计算结果表明该滑坡的稳定性较差,对此提出了相应的防治对策。
Red beds are found in the second member of Badong Formation along Badong bank. The hard rocks are interbedded with soft rocks. The red beds could be interacted with the water penetration. Which causes many landslides in the red beds. As the construction of the Three Gorges Reservoir will bring about many geological hazards, the paper tends to analyse the landslide feature,genetic mechanism and stability of Xirangpoxi landslide. At the same time,it puts forward the control methods.
