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。
Based on the experimental data, this paper discusses the relationship between the uniaxial strength of rock mass and rock mass and the shear strength parameters in the extremely low stress region. Based on the brief introduction of the Hawke-Brown strength criterion, the author proposes the determination. The new method of rock mass constants s and m, and then discussed the approximate determination of the triaxial strength of isotropic and anisotropic rock masses, respectively.
