| 摘 要： | 通过试验阐明了含断续节理岩体的破坏机理，并按断裂力学推导出含断续节理岩体的强度公式，它表明含断续节理岩体的强度有明显的各向异性性质。且按断裂分析推导出霍克强度参数ｍ，ｓ。将以上理论对上湾工程的岩体强度进行了分析，可供工程参考使用。

| Abstract: | This paper studied the damage mechanism of intermittently jointed rock mass through laboratory tests. The formula for the calculation of strength parameters of intermittently jointed rock mass are derived based on fracture mechanics theory. The study shows that the strength of this kind of rock is of apparent anisotropy. Hoek parameters m and s are derived based on fracture mechanics theory and are used in Xiaowan project. |
