［摘要］贵阳北站建筑功能要求在高架候车层周边设置环形高架车道，在商业夹层需要采用大跨度钢桁架跨过车道以满足建筑需要。钢桁架跨度达到31m。结合计算分析，对钢桁架进行了多种方案比较，并最终确定采用M形腹杆布置，下弦支座处采用钢骨混凝土截面的结构布置；对桁架的有利和不利因素做了具体分析。

Abstract: The architectural design of North Guiyang Railway Station requires a circular overhead traffic lane to be loaded around the elevated waiting room level, and the retail mezzanine needs to use large span steel trusses bridging over the traffic lane. The span of the steel truss is 31m. Incorporating the results of computational analysis, several schemes of steel truss were compared. Finally, M shape web members and steel reinforced concrete at the lower chord bearing were adopted in the structural arrangement. The advantages and disadvantages of the truss were analyzed specifically.

Keywords: North Guiyang Railway Station; steel truss; steel reinforced concrete; web member arrangement; closed profiled slab
