摘要
深圳宝安国际机场T3航站楼占地面积约19.5万m2,总建筑面积45.1万m2,南北长约1 128m,东西宽约640m。航站楼主楼下部主体结构为钢筋混凝土框架结构。屋顶采用钢结构,由主楼和呈十字交叉的指廊组成,其中主楼屋顶为倒锥形钢框架柱、钢筒体、以及摇摆柱支承的斜交斜放空间网架结构;指廊采用带加强桁架的斜交斜放的双层网壳结构。针对近海地区基础设计、超长混凝土结构设计、复杂曲面屋顶钢结构设计、超长钢结构体系等结构特点与难点,介绍了结构相关问题的处理措施。
The construction area of Shenzhen Bao＇an International Airport Terminal 3 is about 195 000ms, the terminal spans 640m from east to west and 1 128m from north to south. Total construction area is 0.451 million square meters. Steel-concrete structure was adopted as low-part structure. The roof of the main building is cross truss, which is supported by inverted cone-shaped steel columns, steel cylinder and swing columns. The roof of the cross corridor is cross truss, which is supported by twin bracing truss. The measures to deal with structural problems are introduced such as foundation design for offshore areas, overlong concrete structure design, complex curved roof steel structure design and so on.
