摘要
抽水蓄能电站建设的关键技术问题之一是渗流控制。论文分析了气候等自然地理条件对抽水蓄能电站输水系统所在山体水文地质条件的影响,讨论了钢筋混凝土衬砌及围岩中地下水可能的渗透模式,提出在补水困难、降雨量偏少、岩体质量差、地下水深埋较大的地区,抽水蓄能电站高压水道采用钢衬具有一定的合理性。在高压水道衬砌形式的技术经济综合比选时,建议除了考虑常规的地质条件,还应关注补水工程投入、降雨量等自然地理因素。上述认识对类似工程设计具有一定借鉴作用。
Based on the analysis of the climatic condition around the hydropower tunnel according to different a different climatic conditions.Analyzing the seepage way of water in the waterdiversion system with Concrete lining.The trend of choosing steel penstock in the area of less rainfall area is rational.The results indicate that in the process of steel lining form design optimization,in addition to considering the geological condition of surrounding rock,also should pay attention to the local annual precipitation and annual evaporation capacity,geographical characteristics and hydrogeological conditions.These results have certain value to similar engineering projects.
