摘　　要：随着城市建设的不断发展,地下构筑物日趋复杂,而为了缓解交通拥堵、保证行人过街安全,大跨度人行天桥的应用越来越广泛。如何平衡桥梁设计原则和建设约束条件,已成为城市人行天桥设计中不可避免的难题。为此,以广州市某大跨钢桁架人行天桥的设计项目为依托,对该桥的结构设计、结构计算、对运营地铁的影响等进行了阐述和分析。分析内容可为以后类似工程提供参考。With the continuous development of urban construction,the underground structures are becoming increasingly complex.To alleviate the traffic congestion and ensure the safety of pedestrians crossing the street,the long-span footbridge is more and more widely used.How to balance the bridge design principles and construction constraints has become an inevitable problem in the design of urban footbridge.For this purpose,relying on the design project of a long-span steel truss footbridge in Guangzhou,the structural design,the structural calculation,and the influence on subway operation of the bridge are set forth and analyzed.The analysis content can offer references for similar projects in the future.
