溪洛渡水电站上游近坝库段桥湾变形体滑落影响分析及应急处置措施探讨

On the Potential Consequences and Emergency Treatment of Qiaowan Landslide near the Dam in Upstream of Xiluodu Reservoir

以溪洛渡水库上游永善县雪柏村桥湾变形体为例,通过对变形体监测点合理布置、变形体监测点顺河向、垂直河向及测点竖向沉降位移等监测资料的系统分析,采用潘家铮法对桥湾变形体坠落进行涌浪估算与分析其影响,据此提出了相应的应急处置措施,以探索水电站在应对近坝段库岸滑坡类灾害程度预估与有效性的解决措施。

The potential consequences of Qiaowan landslide near the dam in upstream of Xiluodu Reservoir are analyzed.Firstly,deformation monitoring data of the landslide body are investigated including the parallel and transverse displacements and vertical settlement.Then,the potential landslide surge and its impact are estimated using Panjiazheng Method.Corresponding emergency treatment measures are then proposed.It provides useful reference for the impact estimation and emergency treatment of landslide disasters near the dam in hydropower stations.
