黔中水利枢纽一期工程—平寨水库增设低部位放空设施方案选择

Schemes Selection for Additional Low-level Venting Facilities in Pingzhai Reservoir of the First Phase Project of Qianzhong Water Conservancy Project

根据《混凝土面板堆石坝设计规范》(SL 228-2013)中3.1.6条第4点规定,黔中水利枢纽枢纽一期工程—平寨水库坝高150 m,需增设放空设施,对该工程低部位放空设施方案进行比选,最终推荐采用右岸导流洞改建阀门控制放空方案。结论可对类似工程提供参考。

According to the Article 3.1.6 point 4 of the“Specifications for Design of Concrete Face Rockfill Dam”(SL 228-2013),the Pingzhai Reservoir(dam height 150m)of the first phase of the Qianzhong Water Control Project needs additional venting facilities.Through the comparison and selection of the low-level venting facilities for the project,the final proposal is to add a valve control to rebuild the right bank diversion tunnel for venting.The conclusion can provide reference for similar projects.
