外文摘要：It is found that the mi value changes obviously with the increasing bedding inclination angle and confining pressure. Therefore, the improved Hoek-Brown criterion is proposed by fitting the mi value function relation of bivariate cubic polynomial function considering the bedding inclination angle and confining pressure. Based on the triaxial compression test data of layered phyllite, it is found that the improved Hoek-Brown criterion is effective in predicting the triaxial compressive strength. Based on the improved Hoek-Brown criterion and the damage factor with equivalent plastic strain as the variable, the anisotropic damage constitutive model of layered rock mass (LRM) is established by using the correlated flow law. Through secondary development, the established constitutive model is written into FLAC3D software, and the numerical simulation of triaxial compression test of layered phyllite is carried out. The simulation results show that the developed constitutive model can reflect the anisotropy of layered phyllite effectively. FLAC3D software is then used to analyze the deformation characteristics of layered phyllite tunnel surrounding rock. By comparing with the field test results, it is verified that the developed constitutive model is suitable for the study of deformation and failure of LR|M tunnel surrounding rock. The results show that the developed constitutive model can effectively reflect the anisotropy characteristics of LRM, and is suitable for the study of the deformation and failure of the surrounding rock mass tunnel.
