| 摘 要： | 为客观评价隧道围岩安全状态,结合围岩岩体结构及地质特征等影响因素,建立隧道围岩安全评价指标体系。用ANP法应用Super Decision软件建立指标因素关联图并计算出各指标权重。在传统TOPSIS法的基础上结合相对熵原理,用Kull-back-Leibler距离计算贴近度,构建隧道围岩安全评价模型。运用该模型对张吉怀铁路兰新乡隧道进口段七处隧道段的围岩进行安全性评价,得出各隧道段围岩安全等级,评价结果切合实际,对隧道施工有一定的指导意义。该评价模型简单可操作,可运用于隧道围岩安全性评价研究中。

| Abstract: | In order to evaluate the safety state of tunnel surrounding rock objectively,the evaluation index system of tunnel surrounding rock safety is established by combining with the influence factors such as the structure of surrounding rock mass and geological characteristics.The correlation graph of index factors is established by using ANP method and Super Decision software,and the weight of each index is calculated.Based on the traditional TOPSIS method,the relative entropy principle is added to calculate the closeness degree by using the Kull-back-Leibler distance,and the safety evaluation model of tunnel surrounding rock is constructed.The model is used to evaluate the safety of surrounding rock in seven sections of Lanxinxiang tunnel entrance section of Zhangjihuai Railway,and the safety of surrounding rock of each tunnel section is obtained.The evaluation results are practical and have certain guiding significance for tunnel construction.The evaluation model is simple and operable and can be used in the study of tunnel surrounding rock safety evaluation. |
