摘要
为了解决山区高速公路隧道改扩建方案选取决策困难而又缺乏理论依据的问题,基于直觉模糊数的海明距离,结合TOPSIS方法,增加专家权向量修正,进而得到处理具有优先级别关系的多属性问题的决策方法。分析山区高速公路隧道改扩建的影响因素,建立隧道扩建方案影响指标体系。从依托工程实际出发,邀请指定的专家对指标优先级别排序,然后利用已建的数学模型实现扩建方案寻优。该方法在厦蓉高速公路隧道改扩建施工方案优选中得到有效运用,说明该方法实用可行,对隧道改扩建施工方案以及类似工程方案优选问题具有重要的指导意义。
The determination of rehabilitation scheme of highway tunnel in mountain areas is difficult; and there are few theoretical references. As a result,a determination method for multiple attribute problem with priority relation is put forward based on intuitionistic fuzzy based Hamming distance,TOPSIS method and expert weight vector correction. And then,the influencing factors of the rehabilitation of the highway tunnel in mountain areas are analyzed; and then the influence index system of the tunnel enlargement scheme is established. Finally,the indicators are prioritized by experts invited,and the enlargement scheme optimization is realized by mathematical model established. The successful application of the above-mentioned method to enlargement construction of tunnel on Xiamen-Chengdong Highway indicates that the method is rational and feasible,and can provide reference for tunnel rehabilitation of similar projects in the future.
