城市人行天桥精细化设计的关键问题研究

Research on Key Issues of Fine Design for Urban Pedestrian Bridge

随着城市经济的快速发展,人车交通平面交叉问题日益冲突。人行天桥的建设对于提高车辆运行速度、实现人车分流、改善交通拥挤状况等方面具有良好的交通和社会效益。针对人行天桥的设计工作,从天桥群设计、占地优化设计、结构避让管线设计、经济指标、人性化设计等方面进行剖析和总结,对城市人行天桥的设计理念提出一些建议和方案,希望能为以后的天桥设计提供更多的思路和参考。

With the rapid development of urban economy,the grade intersecting problem of pedestrian and vehicle traffic is increasingly conflicting.The construction of the pedestrian bridges has the good traffic and social benefits in terms of increasing the speed of vehicles,realizing the diversion of pedestrians and vehicles,and the improving the traffic congestion.Aiming at the design of pedestrian bridge,its analysis and summary are carried out from the design of overpass group,optimization design of land occupation,design of structure avoiding pipeline,economic indexes,humanized design and the other aspects.Some suggestions and schemes for the design concept of the urban pedestrian bridges are put forward,which hopes to provide more ideas and references for the design of pedestrian bridges in the future.
