泉州市轨道交通某路段敷设方式模糊优选研究

Research on Fuzzy Optimization of Laying Modes for Some Rail Transit Route in Quanzhou

轨道交通的敷设方式一般有4种:地下线、地面线、高架线和敞开式线路。在线路确定的同时,需要确定轨道的敷设方式。首先对影响选择方式的因素进行分析,确定主要的影响因素,然后根据这些影响因素建立模糊优选系统,利用模糊优选理论对其进行计算,得出该选定路段的最优敷设方式为地下线。

There are four methods for rail transit route laying： underground line, ground wire, high overhead lines and open wide type line. The route is ensured, meanwhile, the rail transit route laying method needs to be ensured. Firstly, the factors influencing selection modes are analyzed to determine the influencing factors. And then according ta these factors, the authors establish the fuzzy optimization system, and the calculation is done using the fuzzy optimization theory, which shows that the optimal laying mode of the selected route is underground line.
