| 英文摘要 | An empirical expression of cohesion (C) and friction angle (phi) for layered rock was suggested. This expression was compared with a test result made by the former researchers. The constitutive relationship of a transversely isotropic medium and Mohr-Coulomb criterion in which C and phi vary with directions were employed, and a relative 3D elasto-plastic FEM code was developed, in which the important thing was to adopt a search-trial method to find the orientation angle (rho) of shear failure plane (or weakest shear plane) with respect to the major principal stress as well as the corresponding C and phi. Taking an underground opening as the calculation object, the numerical analyses were carried out by using the FEM code for two cases of transversely isotropic rock and isotropic rock, respectively, and the computation results were compared. The results show that when the rock is a transversely isotropic one, the distributions of displacements, plastic zones and stress contours in the surrounding rock will be non-axisymmetric along the tunnel's vertical axis, which is very different from that of isotropic rock. The stability of the tunnel in transversely isotropic rock is relatively low. |
