| 摘 要： | 应用RMR分析了岩石的稳定性，同时应用普氏理论对巷道围岩坚固性进行运算，最后运用phase2有限元分析模拟巷道周围应力的分布情况，结合以上三者得出的结果进行比较，得出爱普铁矿巷道稳定性的综合评价，并对巷道维护提出了合理的建议。结果表明，合理的巷道围岩压力分析和模拟，能够正确地反映围岩的分布特征，对今后预测评价巷道稳定有着重要作用。

| Abstract: | RMR is applied to analyze the rock stability,Pullman’s theory is used to calculate the hardness of tunnel wall rocks,finally the phase2 finite element analysis is adopted to simulate the distribution of model stress.Combined with the results from the above three methods,the comprehensive evaluation on the stability of this tunnel of Aipu Iron Mine is obtained and some reasonable suggests to maintain the tunnel are proposed.The results show that the reasonable analysis and simulation on the stress of tunnel wall rocks can reflect the distribution of the wall rocks and provide an important role in predicting and assessing the tunnel’s stability. |
