溪洛渡水电站导流洞卵石推移质测验简介

An Introduction of Gravel Bed-load Testing in the Diversion Tunnel of Xiluodu Hydropower Station

为了寻找溪洛渡导流洞混凝土及钢筋磨损原因,采用缆道悬挂大型采样器方式,在导流洞出口开展卵石推移质试验观测,因此取得通过导流洞的推移质样品,为研究解决导流洞抗磨蚀问题收集了观测成果,也为金沙江后续电站的科研设计提供了有益的资料.

In order to find the reason why concretes and steel bars in the diversion tunnel of Xiluodu were worn out ,this paper introduces a way in which large‐scale samplers suspended on cableways are used to do gravel bed‐load testing at the exit of diversion tunnel .By obtaining gravel bed‐load samples ,this method not only collects valuable information to solve the abrasion problem in diversion tunnels ,but also serves as an essential reference for the design of subsequent hydropower stations in Jinsha River .
