长江三峡库区重庆井泉滑坡体稳定性分析

Chongqing's well spring slope failure stability analysis of Changjiang river three gorges reservoir area

针对重庆井泉滑坡体的现状,分析了滑坡形成机制和破坏模式,进而运用传递系数法进行了滑坡稳定性极限平衡法分析,并进行了工况稳定性验算及工况分析,在此基础上进行了稳定性敏感因素分析,并得出滑坡Ⅰ、Ⅱ区稳定性验算成果,内聚力c值和内摩擦角φ值的变化对稳定系数K的影响。最后指出,滑坡稳定性遭到破坏的主要原因是水位的骤降。

In view of the present situation of Chongqing well spring slope failure its form mechanism and the destruction pattern are analyzed. Further,it has carried out the slope failase limit zero-method analysis using transmission method of correlates,and has carried on the operating mode stability examination and the operating mode analysis and operating mode and the stable susceptibility factor analysis in the foundation and obtain the coast I, II stability examination results,area angle of internal friction c and ψ change to stability coefficient K influence.Last ,it is concluded that the main reason for slope stability destruction is water level plummeting.
