摘要:In order to predict the stability of surrounding rock mass in geotechnical engineering, it is important to study the post-failure deformation property and residual strength of rock mass. Based on evolutional behavior of strength parameters, aiming at generalized Hoek-Brown strength criterion, selecting major principal strain epsilon(1) as strain softening parameter, this paper presents the method of solving post-failure stress-strain curve. In numerical case, the effect of evolutional law of strength parameters m, s and a to deformation and residual strength is discussed and we can draw the following conclusions: the greater the residual values of m, s are and the smaller the residual value of a is, the post-failure strain softening curve falls more gently and the greater the residual strength is.
