Abstract
The elastic mechanics method in foreign specification is applied for design of the lining structure of headrace tunnel.Partial exter-nal hydraulic pressure is considered, but the lining is still designed based on impermeability and calculation is performed by surface force theory.Those result in arrangement of reinforcement in a high quantity.In practice, the lining is already cracked by action of the high inter-nal hydraulic pressure.In operation period, the internal water seeps outward.In repair period, the external water seeps inside the tunnel a-long cracks.Therefore, application of the surface force theory cannot explain the interaction of internal and external water.It is difficult to simulate the stable seepage fields in tunnel and surrounding-rock media.In this paper, the design method with consideration of cracks is ap-plied.Considering the seepage action, the simplified method of the nonlinear calculation applicable for design of lining of the high-head hy-dropower project is proposed.关键词
