摘　　要：以黄河公伯峡水电站工程右岸水平旋流消能泄洪洞为例,采用水工隧洞设计规范的外水压力折减系数法和有限元渗流计算法,对作用于水工隧洞衬砌混凝土上的外水压力值和分布进行探讨,以供同行设计时参考。With the example of the spillway tunnel with energy dissipation of horizontal rotary flow on fight bank of Gongboxia Hydropower Station, values and distribution of external water pressure on the concrete lining of hydraulic tunnel are studied by applications of reduc- tion factor method and finite element seepage calculation method of external water pressure specified in specification for design of hydraulic tunnels.
