摘　　要：乌鲁木齐国际机场T4航站区换乘中心建筑面积约10万m^(2),建筑高度36.5m,具有抗震设防烈度高、温差大、风雪荷载大、结构平面超长、轨交下穿、钢屋盖双向曲面造型等特点。换乘中心采用少墙钢筋混凝土框架结构体系,隔震层设置在基底,屋盖采用大跨单层菱形交叉网格实腹梁体系。介绍了换乘中心若干结构关键问题和设计重难点,包括采用隔震技术的主体结构设计、基础设计、下穿轨交托换设计、典型节点设计。进行了复杂钢屋盖结构传力、抗连续性倒塌及超长单体温度作用分析。结果表明,针对工程特点采取的设计措施安全经济、合理可行。The transfer center in T4 terminal area of Urumqi International Airport has a building area of about 100,000 m^(2)and a building height of 36.5m.It has the characteristics of high seismic fortification intensity,large temperature difference,large wind and snow loads,super-long structural plane,underpass of rail transit,bidirectional curved surface modeling of steel roof,etc.The transfer center adopts a reinforced concrete frame structure system with few walls,the isolation layer is set at the base and the roof adopts a large-span single-layer diamond-shaped cross-grid solid-web beam system.Several key structural issues and key design difficulties of the transfer center were introduced,including the design of the main structure,the design of the foundation,the replacement design of the underpass rail and the design of the typical joints.The force transmission analysis in complex steel roof structure,progressive collapse resistance analysis and temperature effect analysis on super-long single body were carried out.The results indicate that the corresponding design measures taken based on the characteristics of the project are safe,economical,reasonable and feasible.
