摘要
重庆市鱼栏嘴水库引水渠道位于张家沟滑坡地带,2009年暴雨致使引水渠道受到严重破坏。为此,对张家沟的地质条件和滑坡的基本特征、成因和诱发因素以及滑坡破坏模式进行了分析。调查分析认为滑坡为推移型滑坡,形成滑坡的条件包括陡峭的地形条件、松散的滑坡体结构、高强度的暴雨作用,其中,水力因素是形成滑坡的主要影响因素。根据滑坡体稳定性计算分析成果,并依据相关规范要求,对张家沟滑坡治理提供了有针对性的处置措施。
The water diversion canal of Yulanzui reservoir in Chongqing City is located in the area of Zhangjiagou landslide. In 2009, the canal was destructed severely due to rainstorm. In order to guarantee the safe operation of the reservoir, the geological condition of the area and basic characteristics, genesis and inducing factors as well as failure mode of the landslide are analyzed. By the analysis, it is concluded that forming condition for the landslide includes steep landform, loose structure, rich rainwater, in which, the hydraulic condition is the main influential factor; the landslide is caused by thrust load. Based on the analysis resuits, the stability of Zhangjiagou landslide is analyzed according to corresponding specifications and its treatment measures are put forward.
