基于AHP-模糊综合评价法的城市轨道交通无障碍设施服务水平研究——以苏州市轨道交通3号线为例

Research on Service Level of Accessible Facilities for Urban Rail Transit Based on AHP-fuzzy Comprehensive Evaluation Method for Metro Line 3 in Suzhou

摘要:

城市轨道交通无障碍设施服务水平的研究，有利于明确目前城市的发展水平、明确城市未来发展的方向。以苏州市轨道交通3号线为研究对象，基于前期调研阶段收集的各方意见进行分析研究，建立多层次无障碍设施服务水平评估指标体系。评价体系由2个准则层、9个影响因子组成，将模糊数学引入层次分析方法，采用主观与客观、定性与定量相结合的AHP-模糊综合评价法对苏州市轨道交通3号线的无障碍设施服务水平进行评估。结果表明：苏州市轨道交通3号线无障碍设施整体评价为良好，同时以发现的问题为导向，并提出相应改进措施。

Abstract:

Earthquake disaster happens frequently in China. As the traffic lifeline, the seismic safety of urban elevated bridges is particularly important. At present in China, the precast small-box beam and prestressed concrete large-box girder are generally adopted in urban elevated bridges in China. From the perspective of seismic analysis, based on the different seismic stress characteristics of two structural types and the different structural designs, the two structures are compared so as to provide the reference for the selection of urban elevated bridges in the high seismic intension areas.
