［摘要］貴陽北站是我國西南地區(qū)最大規(guī)模的綜合性鐵路交通樞紐，由站房、站臺(tái)雨棚、高架車道等組成。站房采用橋建合一結(jié)構(gòu)。站臺(tái)層承載列車軌道的承軌結(jié)構(gòu)、高架候車層框架標(biāo)準(zhǔn)跨度為21m×24m，商業(yè)夾層與高架候車層柱網(wǎng)上下不對(duì)齊。出站通道層下方有地鐵穿過，在隧道上方的柱通過基礎(chǔ)梁托換。站臺(tái)層承軌結(jié)構(gòu)采用變寬度預(yù)應(yīng)力混凝土框架梁承重。高架候車層采用大跨度預(yù)應(yīng)力混凝土梁，鋼管混凝土柱預(yù)應(yīng)力混凝土梁節(jié)點(diǎn)是保證結(jié)構(gòu)承載力和抗震性能的關(guān)鍵。東西兩端高架車道上方設(shè)置31m跨的鋼桁架，承受冷卻塔等設(shè)備荷載，支承鋼桁架的框架柱采用鋼骨混凝土柱。屋蓋典型跨度42m×66m，采用網(wǎng)架與管桁架相結(jié)合的結(jié)構(gòu)形式。為了發(fā)揮鋼管混凝土柱上段的強(qiáng)度、減小層間位移，支承屋蓋的鋼管混凝土柱頂端與屋蓋結(jié)構(gòu)上下弦均連接。

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.

Keywords: North Guiyang Railway Station; comprehensive transportation hub; bridge-station combined structure; large span; concrete filled steel tubular column; prestressed concrete beam
