模糊综合评价在某互通立交方案设计中的应用

Application of Fuzzy Comprehensive Evaluation in Design of Some Interchange Project

根据某地区地形、地质、相交道路等级和交通流量情况,分别设计了喇叭形立交、子叶式立交、半定向Y形立交三种方案,并采用模糊综合评价对三个立交方案的技术、功能、经济、环境以及管理方面进行综合比较,认为三方案中喇叭形立交方案是最优方案。

According to the terrain, the geology, the category of intersection roads and the traffic flow situation in some area, three interchange projects are separately designed such as the trumpet interchange, the cotyledonal interchange and the partly directional Y interchange. Then the technology, function, economy, environment and the management aspects of three interchange projects are compared comprehensively by using fuzzy comprehensive evaluation, and it is considered that the trumpet interchange is the best project of them.
