| 摘 要： | 在对大冶铁矿龙洞-74m水平巷道现场勘察的基础上,结合现场岩体的物理力学性质和声波测试结果,运用Q指标法、RMR法对巷道围岩进行了分类和稳定性评价。同时运用2D-σ有限元软件对开挖后的巷道进行数值模拟,通过对比数值模拟结果与工程类比法的分类结果,得出优化的围岩稳定性评价结论。

| Abstract: | Based on the engineering geologic investigation on representative tunnel at-74 m level in Longdong zone of Daye Iron Mine and the wall rock's physical and mechanical properties as well as test results of acoustic wave velocity of the wall rock,the paper applies Q and RMR classification methods to determine the quality level of the wall rock of the tunnel and evaluate the stability of the wall rock.In additional to these,the paper applies 2D-finite elements software to simulate the excavated tunnel.Through comparing the results obtained by numerical simulation and engineering analogy,the more dependable evaluation results of wall rock stability have been obtained. |
