甲岩水电站进水口优化设计及应用

Optimum Design and Application of Inlet of Jiayan Hydropower Station

甲岩水电站进水口地形较陡,岩体较完整,可研阶段确定采用岸塔式进水口。施工图阶段,根据现场地形和地质条件,对进水口进行了设计优化调整,进水口闸门部分改为井挖,采用竖井式进水口。优化调整后的进水口体型更符合工程实际,结构更安全合理,并节约工程投资。已于2014年6月底全部机组投产发电,至今运行正常。

The intake of Jiayan hydropower station has steep terrain and complete rock mass, so the towertype intake is adopted in the research stage. In the construction drawing stage, according to the site topography and geological conditions, the design of the intake was optimized and adjusted. The gate part of the intake was changed to well digging, and the vertical intake was adopted.
