［摘要］廣州新客站鐵路樞紐采用站橋合一的結(jié)構(gòu)體系，總平面尺寸525m×586m，建筑面積56萬m²，地下1層，地上3層。首層為地面停車場，屬于室外廣場；層2為鐵路站臺層，采用線性結(jié)構(gòu)為主的預(yù)應(yīng)力鋼筋混凝土結(jié)構(gòu)，中部采用跨度64m的拱形結(jié)構(gòu),平行軌道方向共設(shè)置9道伸縮縫；層3候車室為鋼筋混凝土框架結(jié)構(gòu),其柱子部分落在橋梁上,部分落在橋墩上, 平行軌道方向共設(shè)置2道伸縮縫。屋蓋采用新型大跨度預(yù)應(yīng)力空間鋼結(jié)構(gòu)，主站房屋頂為476m×222m，在屋面與兩側(cè)的無站臺雨棚設(shè)置了伸縮縫。各層結(jié)構(gòu)體系、剛度、質(zhì)量等相差較大，介紹了各層結(jié)構(gòu)特點(diǎn)、相互關(guān)系及其結(jié)構(gòu)布置等。

Abstract:Bridge-station combined structure system is applied in New Guangzhou Railway Station, which is the main building of New Guangzhou Railway Center. The plan dimension is about 525m×586m and the area is 0.56 million square meters. There is one floor underground and three floors overground. The ground floor is parking. The second floor is railway platform, which consists of one dimensional prestress reinforced concrete frame structure and 64m-span arc structure. The third floor is waiting room, which consists of prestress reinforced concrete frame structure, and the columns are supported on bridges or piers. The plan dimension of main station roof consisting of long-span prestress spatial system is 476m×222m, which is separated with canopy roof by aseismic joint. There are 9 aseismic joints in the second floor and 2 in the third floor. The mass and stiffness are greatly different in different floors. The structure system character, interrelation and arrangement are thoroughly introduced.

Keywords: railway station；bridge-station combined system； arc structure; waiting room; prestress; steel structure
