摘　　要：深圳火车北站为京广港铁路上重要枢纽车站之一,总建筑面积18万平方米,由站房和两侧的无柱站台雨棚构成,站房结构不设永久缝,工程体量大,结构复杂。结合建筑功能,雨棚屋盖采用了四边形环索弦支空间结构体系。结合工程项目背景,介绍了该工程结构设计中的关键技术问题,包括结构体系、荷载分析、抗震性能化设计分析、超长结构温差收缩效应分析、高架城市轻轨穿越振动影响分析等。研究结果表明:结构精心设计,能完美实现建筑;轻轨高架穿越,控制列车振动对车站的影响是关键;根据精确的整体有限元分析,予以针对性的加强措施,可有效解决超长结构的温差收缩效应问题;四边形环索弦支结构大大提高了现有弦支结构的工作效率。工程所采用的结构体系对于其它大型公共建筑、尤其是复杂交通枢纽建筑具有很好的借鉴作用。Shenzhen North Railway Station,one of the major hub stations in the Beijing-Guangzhou-Hong Kong railway system,with 180 000 m2 construction area,consists of a central station house and the no-pillar platforms on both sides and adopts an innovative spatial structural system without construction joints.Based on the project background,this paper introduced the key technical issues in the structural design,such as the structural system selection,the loading analysis,the anti-seismic performance design,the analysis of temperature variation and concrete shrinkage effect on super-long structure,the analysis of vibration effect from elevated LRT,etc.Research results show that rational structural design can realize the architecture perfectly.Control of the vibration from the elevated LRT is an important issue for the railway station structure design.Finite element analysis of the overall structure and some special measures can effectively minimize the temperature variation and concrete shrinkage effects on the super-long structure.Quadrilateral string support system largely increases the work efficiency of string supported system in existence.The project can be a reference for similar projects.
