摘　　要：根据模型试验研究结果,深入分析了直剪条件下含共面闭合断续节理岩体的变形和破坏机理,并在此基础上建立了这类岩体的初裂强度和贯通破坏强度准则,将计算结果与实测值进行了对比分析,表明两者吻合较好,证明该强度准则是合理可靠的,具有理论和工程应用价值。On the basis of model testing results,the deformation and fracture mechanism of brittle rockmass containing coplanar close intermittent joints under direct shear condition are analyzed,and the criteria of fracture initiation strength and failure strength of such rockmass are proposed. The calculated results fit in well with experimental results,which indicates that the criteria are reasonable and reliable.
