摘　　要：跨座式单轨交通桥梁多采用小跨径PC轨道梁作为标准梁,在跨越城市道路的节点桥应用上存在诸多问题。本文以某跨座式单轨交通线路为例,对跨越道路处桥梁提出一跨40m钢轨道梁的设计方案,并对钢轨道梁的主要设计参数进行详细的分析和研究,得到受力合理、施工便捷、经济性好的桥梁设计方案,为今后同类工程的设计实践工作提供参考。PC track beam with small span is usually taken as a standard girder in bridge design of straddle type rail transit,that has many problems when the rail lines crossing the urban roads.Based on one rail transit project,a design plan of steel track beam with 40 m span length when crossing urban road was introduced in this paper.Then an overall analysis and comparison was tanken on the main technology parameters,to find a particular design project with reasonable force,convenient construction and low cost.It is also hoped to bring a valuable reference for design and construction of the similar structures.
