Abstract

The Hoek-Brown failure criterion has been widely used for the determination of the strength of intact rock and rock mass in isotropic conditions，but cannot describe the anisotropic characteristics of rock and rock mass. In this paper，an anisotropic failure criterion is proposed based on the Hoek-Brown failure criterion by introducing an anisotropic parameter，which is associated with microstructure tensor a_ij and loading directions l_ij，to the parameters m_b and s，and the sensitivity of parameters used in the anisotropic failure criterion are discussed，and the strength of rocks obtained by the proposed criterion are compared with test results. It is shown that the proposed anisotropic failure criterion can describe the variation of material strength in function of the orientation of the sample relative to the loading direction，and this criterion can be degenerated to the isotropic Hoek-Brown failure criterion. The principle value Ω_i of the deviatoric part of microstructure tensor has a significant effect on anisotropic characteristic of rock mass，and determines the degree of anisotropy. The mean value of microstructure affects the strength of rock mass，and the elasto-plastic parameterhas little effect on anisotropic characteristics of rock mass.
