硬梁包水电站施工导流设计

Diversion Design of Yingliangbao Hydropower Station

硬梁包水电站是四川省大渡河干流水电规划28级方案中的第14个梯级电站,采用引水式开发。挡水建筑物为混凝土面板堆石坝+闸坝。根据坝址地形地质、水文条件及枢纽建筑物布置特点,施工导流方式选定为围堰分期拦断河床,导流明渠泄流。笔者简述了硬梁包水电站施工导流方式与程序,导流建筑物的布置与设计,截流设计等,可供其他工程参考借鉴。

The Yingliangbao Hydropower Station is the 14th cascade hydropower station in the 28 level plan of the main stream of the Dadu River in Sichuan Province,which adopts diversion development.Water retaining structure is composed of concrete face rockfill dam and gate dam.According to the topographical,geological and hydrological conditions of the dam site and the layout characteristics of hydraulic structures,the diversion method is selected as cofferdam to block the riverbed in stages and open diversion channel to discharge.This paper briefly describes the diversion method and procedure of Yingliangbao Hydropower Station,the layout and design of diversion structures,closure design,etc.It can be used as reference for other projects.
