摘要
针对含断续节理岩体强度存在明显各向异性的特点，运用断裂力学理论建立该类岩体霍克－布朗强度参数ｍ，ｓ的数学表达式，证明了ｍ，ｓ值不仅与节理产状有关，而且还是围压σ３的二次函数。最后给出了一个实际工程的典型算例。
Based on the behavior of obvious strength anisotropy of rockmass with intermittent joints, a mathematical formula on the parameters m, s of this kind of rockmass in Hoek-Brown criterion is obtained by using theory of fracture mechanics. It has also been proved that the parameters m, s are not only relevant to the orientation of joints, but also a quadratic function of confining pressure σ3. Finally, a typical example of engineering case is given.
