摘　　要：对高水头大直径钢筋混凝土衬砌压力隧洞的设计准则和结构分析方法进行讨论分析，提出高压隧洞应按不衬砌隧洞进行设计，内压主要由围岩承担，衬砌的主要作用是平整洞壁，防止围岩坍落；外压有可能是衬砌设计的控制情况，增加抗外压圈的厚度能显著提高衬砌抗外压的能力。Based on the design crieria and structural analysis method for large R.C. lined funnels under high water pressure, it is proposed that the fumel should be designed according to the design condition of unlined tunnel, and the internal pressure undertaken mainly by the surrounding rock. The function of R.C. lining is mainly to smooth the tunned and to prevent the surrounding rock from collapse. The design of the tunnel often depends on external water pressure. Increasing the lining thickness can enhance obviously its ability to bear the external pressure.
