［摘要］溫州世界貿(mào)易中心由塔樓和裙房組成，其中塔樓為69層鋼筋混凝土超高層建筑，結(jié)構(gòu)高度接近278m，建筑高度333.33m。由于結(jié)構(gòu)兩部分地下室是連為一體的，而基礎(chǔ)巖層厚度和高低變化較大，通過加深基樁進(jìn)入強(qiáng)風(fēng)化基巖的深度，使單樁承載力與持力層為中風(fēng)化基巖的基樁承載力相近，達(dá)到控制整體建筑物均勻沉降的目的。上部結(jié)構(gòu)底部為框架核心筒，上部為筒中筒，采用分支柱的結(jié)構(gòu)過渡形式，達(dá)到豎向結(jié)構(gòu)均勻過渡。

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
