摘　　要：为合理设计钟祥抽水蓄能电站输水系统,详细介绍了钟祥抽水蓄能电站输水系统的设计情况,依据工程枢纽布置,结合地形地质条件,确定了输水系统布置线路。根据工程特点,选择了合适的进/出水口型式,并进行结构设计,以优化水力条件。通过技术经济比选,确定了引水隧洞采用竖井布置、洞径5.5 m的设计方案。考虑开挖洞径、沿线地质条件不同,对各洞段的支护参数进行了设计,达到安全、经济的目的。运用非线性有限元方法,对各工况下的引水隧洞进行了结构分析,计算结果表明,引水隧洞结构满足安全要求,配筋结果合理。研究成果可为类似输水系统设计提供参考。For the rational design of Zhongxiang Pumped Storage Power Station water transmission system,we provided a detailed introduction to the design of the water conveyance system for the station.Based on the layout of the engineering hub and the terrain and geological conditions,the layout route of the water conveyance system was determined.According to the characteristics of the project,suitable inlet/outlet types were selected and structural design was carried out to optimize hydraulic conditions.Through technical and economic comparison,the design scheme of using vertical shafts with a diameter of 5.5 m for the diversion tunnel had been determined.Considering the different excavation diameters and geological conditions along the route,the support parameters for each tunnel section had been designed to achieve the goals of safety and economy.The non-linear finite element method was used to perform structural calculations on the water diversion tunnel under various working conditions,and the results showed that the structure of the water diversion tunnel could meet safety requirements and the reinforcement results were reasonable.The research results can provide a reference for the design of similar water conveyance systems.
