万家口子水电站碾压混凝土双曲拱坝排水系统设计

Design of Drainage System for RCC Double Curvature Arch Dam of Wanjiakouzi Hydropower Station

云南万家口子碾压混凝土双曲拱坝排水系统由坝体排水、坝基坝肩排水和两岸抗力体排水组成。笔者简略介绍大坝坝体排水、坝基坝肩排水和两岸抗力体排水设计方案。从电站运行后实际渗水情况来看,大坝排水系统设计是合理有效的。

The drainage system of Wanjiakouzi RCC double curvature arch dam in Yunnan Province consists of dam body drainage,dam foundation abutment drainage and resistance body drainage on both banks.This paper briefly introduces the design scheme of dam body drainage,dam foundation abutment drainage and resistance body drainage on both banks.According to the actual seepage situation after the operation of the power station,the design of the dam drainage system is reasonable and effective.
