Abstract: 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.
