| 摘 要： | 如何评价工程岩体中赋存的应力状态一直是工程设计人员所要面对的基本问题之一.应力状态评价需综合考虑岩体强度和岩体中赋存的应力两个要素,其评价结果反映了地下结构围岩在二次应力场作用下满足岩体强度准则时可能的变形破坏响应.通过对前人研究成果的分析,总结出高应力作用下地下结构的基本变形破坏规律.利用Hoek-Brown强度准则...

| Abstract: | How to evaluate the stress state in an engineering rock mass is one of the most fundamental problems that all the underground structure designers have to be faced with.Evaluating the stress state needs considering both sides of this problem,rock mass strength and stresses in the rock mass.The evaluation results reflect the deformation and failure responses of surrounding rock masses under the actions of secondary stresses when they observe a rock mass strength criterion.Most research findings in the past on... |

| Keywords: | high stresses strength criterion ratio of strength to stress in-situ stresses |
