规则节理化岩体的强度具有方向性.其特征取决于相对于加载方向的节理方位,以及所施应力状态的性质和各向异性.本文提出了以分析解来描述在野外可能遇到的包括一个或几个应力分量为张应力的全范围应力状态下规则节理化岩体的强度。完整岩石强度可用Hoek和Brown判据来描述;节理不具抗拉强度且抗剪强度由库伦判据来描述.本文分析了在双向及轴对称加载条件下上述参数对节理化岩体的影响.
The strength of the regular jointed rock mass is directional and its characteristics depend on the joint orientation relative to the loading direction and the nature and anisotropy of the applied stress state.This paper presents an analytical solution to describe the possible problems encountered in the field including One or several stress components are the strength of regular jointed rock mass under full tension stress. The complete rock strength can be described by the Hoek and Brown criterion. The joints have no tensile strength and the shear strength is described by Coulomb criterion. The effect of the above parameters on the jointed rock mass under two-way and axial symmetric loading conditions is analyzed.
