摘　　要：根据《城市轨道交通线网规划标准》基本原则,总结城市轨道交通线路敷设方式经验,提出三阶段线路敷设方式比选方法,即关键节点/区段敷设方式、敷设方式适应性评价、经济性比选。基于模糊层次分析法的基本原理,结合济南人文、地理、环境要素,提出基于改进的模糊层次分析方法的敷设方式适应性评价方法及算法,形成三阶段模糊层次线路敷设方式比选方法。应用该方法研究济南轨道交通1号线线路敷设方式。结果表明:经关键节点/区段分析,可判定方特站至京沪铁路水屯站区间,4座车站均为地下站,区间采用地下敷设(盾构工法);经基于模糊层次分析的敷设方式适应性评价,在京沪铁路水屯站至工研院站区间,地下敷设、高架敷设隶属度分别为0.499、0.501,两种敷设方式无显著差别;经经济性比选,在京沪铁路水屯站至工研院站区间,高架敷设比地下敷设静折现值节省42.4%,建议选用高架敷设,这与实际结果一致。Based on the basic principles of Standard for urban rail transit network planning,a three-stage line laying mode by means of the experience in laying urban rail transit lines is put forward,that namely key node/section laying mode,adaptability evaluation of laying mode and economic comparison.Based on the basic principle of fuzzy analytic hierarchy process,combining with the characteristics of Jinan cultural and geographical environment,the adaptability evaluation laying method and algorithmis put forward and three-stage fuzzy hierarchical line laying mode is formed.The study on the laying mode of Jinan rail transit line 1 shows that:through the analysis of key nodes/sections,it can be determined that the four stations between Fangte station and Shuitun station of Beijing-Shanghai railway are underground stations,and the underground laying(shield construction method)is adopted in the interval.According to the adaptability evaluation of the laying method based on fuzzy hierarchical analysis,the membership of underground laying and elevated laying between Shuitun station of Beijing-Shanghai railray and Gongyanyuan station is 0.499 and 0.501 respectively,and there is no significant difference between the two laying methods.According to the economic comparison,the overhead laying can save 42.4%compared with the static discounted present value of underground laying between the Shuitun station of the Beijing-Shanghai railway and Gongyanyuan station,so it is suggested to choose the overhead laying,which is consistent with the actual result.
