摘要
采用双剪统一强度理论,考虑中间主应力影响,建立了压力隧洞围岩抗力系数K的计算方法,给出了其相应解析计算式,并退化到莫尔–库仑屈服模型、特雷斯卡屈服模型,验证了所获成果的正确性与通用性。
By use of the unified strength theory, a method to calculate the resistance coefficient K of adjoining rock for pressure tumels was established considering effect of intermediate principal stress. The corresponding equations were given. They were degenerated to the Mohr-Coulomb yield model and Tresca yield model. The accuracy of test results were verified.
