摘　　要：青岛北站为特大型铁路客运站和综合性交通枢纽,主体结构由主站房（屋盖、高架候车层、东西广厅）和两侧对称的站台无柱雨棚组成。主站房屋盖东西长约350m,南北宽约168~213m,由10榀立体拱架组成,跨度为101.2~148.7m不等,最大悬挑约30m。高架候车层平面尺寸约为154m×275m。主要介绍了该项目在结构设计过程中所解决的主要问题,包括三维立体拱架结构体系研究、高架候车层、观景平台、幕墙钢架和无柱雨棚结构设计以及东西广厅耗能减震设计;同时介绍了结构设计中进行的缩尺模型试验、异形截面试验和耐火试验等。Qingdao North Railway Station is a megalopolis railway station and comprehensive transportation junction.The major structure consists of the main station（roof,elevated waiting room floor,west and east halls） and no-column platform canopy set symmetrically on both sides.The main station roof is about 350m long and 168m to 213m wide,and it consists of 10 three-dimensional arches in span of 101.2m to 148.7m（the largest cantilever arch is about 30m long）.The elevated waiting room floor is about 154m × 275m in plane size.The main problems solved in the design of this project were introduced,including structural system research of three-dimensional arch structure,elevated waiting room floor design,viewing platform design,curtain wall steel frame design,no-column platform canopy structure design and energy dissipation design of west and east halls.Model scale tests,abnormal section tests and fire resistance test were introduced as well.
