| 摘 要： | 首先对多裂隙岩体的损伤加以定义，在建立裂纹扩展时产生等效次生裂纹模型的基础上，对多裂隙岩体受荷后发生断裂损伤时其演化方程进行探讨，最后通过大型岩体相似模型试验对理论计算结果分析验证，理论计算与试验结果吻合较好。

| Abstract: | In this paper,the damage tensor of multi-crack rock mass is defined.The idea is proposed independently that the equivalent sub-cracks appear while a crack develops.The evolution equation of multi-crack rock mass is studied.Finally,the theory proposed in this paper is verified through the test of large rock mass similarity model,whose resultS coincide well with the theoretical analysis. |
