［摘要］温州世界贸易中心由塔楼和裙房组成，其中塔楼为69层钢筋混凝土超高层建筑，结构高度接近278m，建筑高度333.33m。由于结构两部分地下室是连为一体的，而基础岩层厚度和高低变化较大，通过加深基桩进入强风化基岩的深度，使单桩承载力与持力层为中风化基岩的基桩承载力相近，达到控制整体建筑物均匀沉降的目的。上部结构底部为框架核心筒，上部为筒中筒，采用分支柱的结构过渡形式，达到竖向结构均匀过渡。

Abstract:Wenzhou World Trade Center is composed of tower and podium. The tower is a 69-stories super high-rise building which was built by reinforcement concrete, and its height is 333.33m. The structural design was introduced. The basement of the two parts is a whole and the situation of ground base is complex. Bored-piles penetrated into strongly weathered rock were deeper than those located on medium weather rock, so as to achieve uniform bearing capacity to control the settlement of the whole building. Branch-columns were employed for structural transfer and no outriggers were needed to increase lateral rigidity of the structure.

Keywords:super high-rise building; pile-mat foundation; transfer stories
