摘　　要：抽水蓄能电站大多水头较高,输水管道长度较长,其高压隧洞采用不同的衬砌形式对工程安全和工程造价有着较大的影响,因此,隧洞衬砌形式的选择尤为重要。抽水蓄能电站高压隧洞常用的衬砌形式主要有钢筋混凝土衬砌和钢板衬砌2种。该文结合云霄抽水蓄能电站的水文地质条件,吸收已建工程的成功经验,通过技术经济比选,最终选定采用钢筋混凝土衬砌形式。Most of the pumped storage power stations have high water heads and long water pipelines.Different lining types of high-pressure tunnels have great influence on engineering safety and cost,so the selection of tunnel lining types is particularly important.The common lining types of high pressure tunnel in pumped storage power station are mainly reinforced concrete lining and steel plate lining.Combined with the hydrogeological conditions of Yunxiao pumped storage power station,absorbing the successful experience of existing projects,and through technical and economic comparison,the reinforced concrete lining scheme is finally selected in this paper.
