摘　　要：分析天荒坪抽水蓄能电站上游高压隧洞观测仪器在充排水试验过程中所记录的实测资料,讨论高压隧洞围岩承载、衬砌构造配筋、衬砌与围岩之间缝隙随内水压力增加而增加等隧洞渗透体积力理论概念,期望通过实测资料来进一步理解和说明高压隧洞渗透体积力理论,以便更好地指导设计。Observed data from a water filling and drainage test in the upper stream high-pressure tunnel of the Tianhuangping pumped-storage power station are analyzed. Several theoretical concept of tunnel permeation volume strength are discussed, such as the the surrounding rock bearing strength, the constructional reinforcement of the tunnel liner, and the increase of the gap between the liner and the tunnel with internal water pressure. The goal is to explain the theory of permeation volume strength in a hlgh-pressure tunnel with observed data, so as to provide better guidance for tunnel design.
