［摘要］贵阳北站是我国西南地区最大规模的综合性铁路交通枢纽，由站房、站台雨棚、高架车道等组成。站房采用桥建合一结构。站台层承载列车轨道的承轨结构、高架候车层框架标准跨度为21m×24m，商业夹层与高架候车层柱网上下不对齐。出站通道层下方有地铁穿过，在隧道上方的柱通过基础梁托换。站台层承轨结构采用变宽度预应力混凝土框架梁承重。高架候车层采用大跨度预应力混凝土梁，钢管混凝土柱预应力混凝土梁节点是保证结构承载力和抗震性能的关键。东西两端高架车道上方设置31m跨的钢桁架，承受冷却塔等设备荷载，支承钢桁架的框架柱采用钢骨混凝土柱。屋盖典型跨度42m×66m，采用网架与管桁架相结合的结构形式。为了发挥钢管混凝土柱上段的强度、减小层间位移，支承屋盖的钢管混凝土柱顶端与屋盖结构上下弦均连接。

Abstract: As the largest comprehensive railway transportation hub project in the southwest of China, the North Guiyang Railway Station is composed of main station building, platform shed, elevated highway and so on. The main station building adopts bridge-station combined structure frame. The standard frame size of the platform floor and the overhead waiting floor is 21m×24m. Column of the commercial mezzanine can not align with the column of the overhead waiting floor.Subway metros pass under the out station floor, so the pillars upon subway tunnel are transferred by foundation beam. The platform floor adopts varied-width flat prestressed concrete beam, and the overhead waiting floor chooses large-span prestressed concrete beam. A new joint of concrete filled steel tubular column-prestressed concrete beam was designed to make sure the structure have better bearing capacity and seismic behavior. Steel trusses with the span of 31m are used to bear the cooling tower and other equipment loads, which cross upon the overhead roadway on the east and the west,and are supported by steel reinforced concrete columns. The combination of pipe truss and steel girder structure was used to the roof of the station with typical column span 42m×66m. To give full play to the strength of steel pipe, and decrease the interstory displacement, the upper and down chords are welded to the concrete filled steel tubular column which supports the roof structure.
