摘要
溧阳抽水蓄能电站引水钢岔管HD值大,围岩地质条件较差(以Ⅳ类围岩为主),岔管的设计及施工是工程的关键技术问题之一。如何保证钢岔管的结构安全、施工方便和经济合理,是设计中必须解决的问题。在可行性研究阶段及可研设计审查后,对岔管的设计及施工方案进行了大量的计算分析和研究工作,对岔管的结构特性、水力特性、施工特性有了较全面的认识和了解。目前岔管的设计方案和施工方案可满足工程应用的要求。
The diversion steel bifurcation of Liyang Pumped-storage Power Station has higher HD, and the main surrounding rock is class Ⅳ rock. The design and construction of the bifurcation is one of the key technical issues. In the design of bifurcation, the structural characteristics, hydraulic characteristics and construction features were analyzed, and got a more comprehensive knowledge and understanding on it. The current design and construction programs can ensure safe structure, convenient construction and reasonable cost.
