某水库工程枢纽布置设计

Layout Design of a Reservoir Project Hub

青海省海东市乐都区杨家水库水源主要有上水磨沟水和引大济湟的调水,是一座供水、灌溉的综合性工程。杨家水库工程枢纽建筑物由拦河大坝、泄水建筑物、放空洞和引水建筑物等部分组成。拦河大坝通过对混凝土面板堆石坝、壤土心墙堆石坝和碾压混凝土坝比较推荐面板堆石坝为挡水建筑物推荐方案;泄洪建筑物通过对洞室溢洪道和开敞式溢洪道进行比选推荐洞室溢洪道作为泄洪建筑物推荐方案。放空洞采用导流洞后期改建,比选岸边塔式方案和竖井方案,推荐竖井方案。杨家水库枢纽布置合理经济,为同类工程提供参考依据。

Yangjia Rreservoir in Ledu District,Haidong City,Qinghai Province is a comprehensive project for water supply and irrigation,whose water sources mainly from Shangshuimogou water and water diversion from Daji to Huanghe River.The key structures of Yangjia Reservoir Project are composed of dam,drainage structure,discharge tunnel and water diversion structure.Through the comparison of concrete face rockfill dam,loam core wall rockfll dam and roller compacted concrete dam,it is recommended that concrete face rockfill dam be the recommended scheme of water retaining structure.Through comparison and selection of the tunnel spillway and the open spillway,the tunnel spillway is recommended as the recommended scheme of the flood discharge structure.The diversion tunnel will be used in the later stage of reconstruction of the emptying tunnel.The tower scheme and the shaft scheme of bank are compared and the shaft scheme is recommended.The layout of Yangjia Reservoir is reasonable and economical,which provides a reference for similar projects.
