摘　　要：在武汉轨道交通21号线第三标段桥梁施工时,采用承载能力强、拼装简便、设计科学的贝雷桁架做主梁,钢管桩作为基础的便桥。利用既有3×1.5×1.2m贝雷桁架、准Ф529×8mm钢管桩,结合工程实际,对便桥结构进行承载验算及优化,满足施工荷载要求并减少施工成本。During the construction of the third section of the No. 21 line of Wuhan Rail Transit, the Berray truss with strong bearing capacity, simple assembly and scientific design is used as the main beam, and the steel pipe pile is used as the basic bridge. The existing 3× 1.5 × 1.2 m Berray truss and Ф529 × 8 mm steel pipe piles are used, combined with the actual project, carrying out the calculation and optimization of the bearing structure of the bridge, to meet the construction load requirements and reduce construction costs.
