［摘要］长春龙嘉国际机场T2航站楼平面呈人字形布局，主体为钢筋混凝土框架结构，屋盖采用四角锥网架结构，采用锥形柱支承。结合场地情况，对±0m标高以下的回填压实桩基础方案和地下架空桩基础方案两种方案进行对比，确定能减少桩的负摩阻效应的地下架空桩基础方案为最优方案。结合建筑特点，屋盖采用网架结构能较好地实现建筑造型，同时尽量控制各结构单元尺寸，以减弱行波效应对结构产生的扭转影响。结合出发大厅空间特点，采用索网幕墙的立面方案，使建筑立面更为简洁，采用有效措施解决了超长索网幕墙在结构变形缝处变形协调问题。

Abstract:The plane of  Changchun Longjia International Airport T2 Terminal  is a herringbone layout. The structural system is a reinforced concrete frame, and the roof adopted square pyramid space grids, supported by tapered columns. According to the situation of site, the two schemes of the backfill compacted pile foundation scheme and the underground overhead  pile foundation scheme below ±0m elevation were compared, and the underground overhead  pile foundation scheme which can reduce the negative friction effect of the pile is determined as the optimal scheme. According to the characteristics of the building, space truss roof structure can better achieve the building shape, and at the same time the size of each structural unit was controled as much as possible to weaken the torsional effect of the traveling wave effect on the structure. According to the space characteristics of departure hall, the scheme of cable net curtain wall facade was selected to make a more concise fa-ade. Effective measures were adopted to solve the problem of deformation coordination of the super long cable net curtain wall.

Keywords:Changchun  Longjia International Airport; negative friction; cable net curtain wall; deformation coordination
