高寒高海拔地区小型水电站压力前池设计与优化

Design and Optimization of the Forebay in Small Hydropower Stations in High Altitude and Cold Area

针对新疆高海拔高寒地区的实际情况,在确定阿克塔木水电站工程压力前池布置形式的基础上,对压力前池结构布置进行了比选,分析了不同条件下压力前池的运行工况、施工条件和工程投资等方面的差别,确定了侧向进水、正向排冰的方案,进行了对应方案的水力、整体稳定性以及基础承载力等方面的设计与校核,相关设计成果可为同类工程提供参考。

Considering the practical working condition of the Aketamu Hydropower Station,which is located in the high altitude and cold area of Xinjiang Uygur Autonomous Region,design and optimization of the forebay are introduced. A detailed comparison is made on the operational conditions,construction conditions and investment of different design schemes. The scheme with side water inlet and forward ice discharging is then selected. Correspondingly,the hydraulic and overall stability and the foundation bearing capacity are checked. The relevant design results could be a useful reference for similar projects.
