| 摘 要： | 本文以试验资料为依据,论述了岩块和岩体的单轴强度与极低应力区剪切强度参数之间的相互关系,并在简要介绍霍克—布朗强度准则的基础上,提出了确定岩体常数s与m的新方法,进而分别讨论了各向同性和各向异性岩体三轴强度的近似确定问题。

| Abstract: | This paper deals, firstly, with the relationship between the uaiaxial compressive strength of intact rocks and rock masses and their Mohr-Coulomb shear strength parameters under very low stress conditions Hoek-Brown strength criterion is then inlroduced briefly,Anda new method in determining constants, s and m, of rock masses is presented.Further, the axial strength of isotropic and anisotropic rock masses under the triaxial state of stress is discussed respectively. |
