基于AHP和模糊熵的高速公路隧道重要度评价

Importance Assessment Model for Highway Tunnel Based on Analytic Hierarchical Process and Fuzzy Entropy

在高速公路管理中,如何针对不同类型、不同区域、不同建设规模等数量繁多的隧道制定针对性、差别化的管理方案是管理部门的难题之一。本文通过参考国内外已有的研究成果,开展对高速公路隧道重要度影响因素的深入分析,提出六个重要度评价指标:隧道土建结构,隧道长度,隧道路面状况,隧道交通量,绕行距离,雨、雾、冰雪天气,并通过采用AHP方法与模糊熵法确定各指标权重,建立了完整的隧道重要度评价方法,使隧道管理部门能够根据高速公路中隧道重要度的差异,制定相应的管理方案。

It is one of management maintenance on. Referring to the ex the difficulty problems for highway managers to make different plans according to tunnel type, region, construction scale and so isted research results at home and abroad, this paper conducted a deep analysis for the factors affected the importance of the highway tunnel, and proposed six importance evaluation indicators： that were tunnel civil structure, tunnel length, tunnel pavement condition, tunnel traffic, detour distenance and severe weather. The weight coefficients of the evaluation indexes were calculated by using AHP and the fuzzy entropy method. With this evaluation method, highway managers can make maintenance plans more objectively and effectively according to the importance of the highway tunnel.
