【摘要】 压力隧洞的弹塑性分析，工程上一直采用Mohr－Coulomb强度准则进行分析。由于该准则只能解决某一类材料的屈服问题，因此适用范围有限。本文采用统一强度理论对该问题进行分析，解决了这个问题。更多还原

【Abstract】 Mohr-Coulomb strength theory has been used to analyse pressure tunnel in the field of rock engineering for many years. Because it could only solve the problemes with one kind of material, the application of the theory was greatly restricted. In this paper, alled strength theory was applied and the tunnels composed of different kinds of materials could be analysed.更多还原
