Abstract:

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.

Key words: XiamenChengdong Highway, mountain areas, tunnel enlargement, Hamming distance, intuitionistic fuzzy sets
