摘要
奉节县向家淌滑坡是一个由碎裂岩体构成的岩质滑坡,由老滑坡体和其上的次级滑坡体构成。三峡水库运行后,向家淌滑坡的稳定性降低,次级滑坡将处于欠稳定状态,其前部可能会发生较大规模的滑动。根据滑坡特征、主导诱发因素和稳定性,针对滑坡失稳特征,通过防治方案初选,初步拟定了搬迁避让方案和综合工程治理方案,并从技术经济方面对比分析论证,确定了由抗滑桩工程、地表排水工程、块石护坡工程等组成综合治理方案,布置于变形破坏强烈的次级滑坡地段,以保证滑坡体稳定,根除危害。
Xiangjiatang landslide in Fengjie is a rocky landside made up of a smashed rock mass,constituted by old landslide and its secondary landslides.After the Three Gorge Reservoir running,the secondary landslide will be unstable.Therefore it should be controlled.According to its complicated geo-structure and formation mechanism,the controlling project is very difficult.Based on studying the characteristics,the magistral trigger factors and the stability of Xiangjiatang landslide aim at its stability,and through primarily selection of the more optimum controlling schemeint study the allthor draws out the controlling system consisting of resistance pile project,upper draining project,rock block protecting-slope project,which are arranged where the slope is strongly failure in order to ensure stability of the landslide.At last accomplishes the construction design.
