摘　　要：对古瓦水电站引水隧洞浅埋高压段进行二维有限元渗流场计算,通过对古瓦水电站两个过沟浅埋段不同工况下引水隧洞钢衬长度的敏感性分析,论证原设计钢衬长度的科学合理性,为类似引水隧洞工程提供借鉴经验。In this paper,seepage of the shallow buried high-pressure section of the headrace tunnel of Guwa Hydropower Station is calculated by two-dimensional finite element method.Through sensitivity analysis on the length of the steel lining of the headrace tunnel in different working conditions of the two shallow buried sections of Guwa Hydropower Station,the length of the steel lining originally designed is proven to be reasonable and this paper provides reference for similar headrace tunnel engineering.
