| 摘 要： | 针对钻爆法隧道施工过程中坍塌风险事件频发、影响因素众多,且目前已有评估方法难以对其作出准确分析,为了考虑到风险因素间的相互影响及其模糊性与不确定性,提出一种基于模糊网络分析法(FANP)的钻爆法隧道坍塌风险评估方法.通过收集和整理隧道坍塌资料,以风险分解结构(RBS)的思路构建钻爆法施工隧道坍塌风险评价指标.基于网络分析法建立模糊加权超矩阵,计算极限超矩阵求得权重向量.最后根据最大隶属度得到坍塌风险的大小.该模型在福建莆炎隧道得到验证,其分析结果可信.

| Abstract: | In view of the frequent occurrence of collapse events and many influencing factors during the process of drilling and blasting tunnel construction,as well as it is very difficult to accurately analyze them with existing methods.A method for evaluating the collapse possibility of construction tunnel by drilling and blasting method based on fuzzy analytic network process(FANP)is developed to consider the mutual influence of risk factors and their ambiguity and uncertainty.According to the collected data of tunnel collapse,the risk assessment indices of tunnel collapse by drilling and blasting method are constructed by risk breakdown structure(RBS)method The fuzzy weighted super matrix is constructed based on network analysis,and the weight vector is obtained by calculating the limit super matrix of the super matrix.Finally,the score of the collapse risk is obtained according to the maximum membership.The validity of the FANP model was verified through applying it to Fujian Puyan Tunnel. |
