大渡河流域某水电站倾倒变形体边坡治理措施探索

Study on the treatment measures of dumping amoeba slope of a hydropower station in Dadu River Basin

倾倒变形体边坡通常构造复杂,稳定性差,在水电站施工的过程中,如何有效对其进行治理,往往是电站建设期安全和进度控制的难题。以大渡河流域某水电站位于倾倒变形体范围内的导流洞进口边坡为例,结合倾倒变形体边坡特性描述、变形过程以及采取的治理措施,以期为相似工程倾倒变形体边坡治理提供借鉴。

Dumping Amoeba slopes are usually complex in structure and poor in stability.During the construction of hydropower stations,how to effectively manage them is often a difficult problem in the safety and progress control of the construction period of power stations.This paper takes the diversion tunnel inlet slope of a hydropower station in the Dadu River basin,which is located within the scope of dumped Amoeba,as an example,combined with the description of the characteristics of dumped Amoeba slope,the deformation process and the treatment measures taken,in order to provide a reference for the treatment of dumped Amoeba slope of similar projects.
