乐昌峡水库鹅公带滑坡体滑坡涌浪影响研究

Research on effect of landslide surge of Egongdai landslide body in Lechangxia reservoir

鹅公带滑坡体位于乐昌峡水库库区上游约1.3 km的右岸侧,库区河道狭窄,滑坡涌浪会对库区岸坡和挡水大坝等产生明显不利的影响。根据鹅公带滑坡体分布的特点,对其滑坡涌浪影响进行水力模型试验,模拟了滑坡体的下滑过程和滑坡速度,对滑坡涌浪的浪高、漫坝涌浪水量、挡水大坝的涌浪动水压强等特性进行分析,成果可供工程设计和运行参考。

Egongdai landslide body is located in the upstream 1.3 km of right bank of Lechangxia reservoir area, the river of reservoir area is narrow, the landslide surge will obviously produce bad effects on the reservoir bank slope and water - retaining dam ect. According to the distribution characteristics of Egongdai landslide body , the article carried out the hydraulic model test of landslide surge, simulated landslide process and speed, and analyzed the characteristics of landslide surge wave height, overtopping surge water, and surge dynamic water pressure intensity. The result can provide reference for the design and operation of project.
