Abstract：
The existing slip-line theory mostly uses the Mohr-Coulomb failure criterion to solve problems of the ultimate bearing capacity of soil and slope stability for soil. In solving the questions of the bearing capacity and stability of rock mass, the existing theory of slip-line is applied to solve in the strength of the rock mass damage problem has many shortcomings. In this paper, based on the classical (D-P) failure criterion for rock mass, considering the nonlinear characteristics of rock mass failure curve and the influence of intermediate principal stress, a parameter m for intermediate principal stress is introduced and the slip-line theory for rock mass is deduced, slip-line theory can more accurately applied to the rock, and connecting with an example, the derivation of the formula is verified finally. For the slip-line method is used to solve the bearing capacity of rock slope and batholith rock damage problems, such as theory basis.
