摘要
为了对上软下硬地层的隧道施工风险进行评估与分析,运用WBS-RBS方法建立一个全面的风险评估指标体系,通过D-AHP方法来进行评价指标权重的计算.运用灰色理论来求解灰色评价矩阵.在这两种方法结合的基础上,对上软下硬复合地层的隧道施工进行综合评估,并直观地表示出风险的评估结果.通过实例对此分析,运用D-AHP方法和灰色理论相结合的风险评估方法能够有效地解决评估信息不确定性问题以及评估过程信息资源不足的灰性特征,计算方法简便,风险评估结果量化,对复合地层隧道施工的风险评估具有参考价值.
In order to evaluate and analyze the tunnel construction risk of upper soft and lower hard stratum,a comprehensive risk assessment index system was established by using the WBS-RBS method,and the weight of the evaluation index was calculated by the D-AHP method.Grey evaluation matrix is solved by grey theory.On the basis of the combination of the two methods,the tunnel construction in the upper soft and lower hard composite stratum is comprehensively evaluated,and the result of risk assessment is presented intuitively.Through example analysis,the use of D combining AHP method and grey theory of risk assessment method can effectively solve the problem of uncertainty evaluation information and the evaluation process the gray feature of the information resources,the calculation method is simple,quantitative risk assessment results,on the risk assessment of compound formation tunnel construction has a reference value.
