引子渡水电站枢纽布置及特点

Pivot Layout & Its Features of Yinzidu Hydropower Station

引子渡水电站枢纽工程由混凝土面板堆石坝、左岸溢洪道、发电引水隧洞、厂房等水工建筑物组成。在地形上无天然桠口可供利用 ,采用大开挖形成溢洪道 ,开挖石碴用来筑坝 ,不仅解决了大流量泄洪问题 ,还节省了工程投资 。

The pivot of Yinzidu Hydropower Station consists of a concrete face rockfill dam, a spillway on the left band, conduit tunnels, and a powerhouse. There are not any natural valleys in topography that can be utilized in its layout. The methods using great excavation to form spillway, and using the rock excavated to fill dam not only solve the problem of flood relieving in big discharge, but also reduce the engineering cost and protect ecologic environment of the dam site.
