| 摘 要： | 奉节县安渡滑坡正处于蠕滑变形-加速变形阶段,其破坏力极大、影响甚广.本文在深入分析滑坡地质特征、结构特征和变形特征的基础上,对滑坡的成因机制和影响因素进行了深入研究.采用传递系数法计算并评价其稳定性.研究表明,安渡滑坡体目前处于不稳定状态,三峡水库蓄水到175m或遭遇长时间高强度的暴雨时,可能整体失稳.

| Abstract: | Andu landslide, located in Fengjie County of the Three Gorges Reservoir area, is just placed in the stage of wriggling transmutation to the acceleration transmutation, whose destructiveness and influence are great and wide and the circumstance is more urgent. This paper introduces the characteristics of geology, structure and deformation of the landslide. Meanwhile, the formation mechanism and influencing factors of the landslide are deeply analyzed. This paper adopts transfer coefficient method to calculate and evaluate the stability. According to study, the Andu 1 # and 2 # landslide are placed in the unsteady condition currently. When the water level of the Three Gorges Reservoir reaches 175m or it suffers sustaining rainstorm, the landslide maybe collapses entirely. |
