摘要: 华润温州老港区二期主塔楼为高 300m 的钢筋混凝土框架￣核心筒结构，底部采用钢管混凝土叠合柱。 项目位于临江高风压地区，高宽比接近 7. 5，抗风设计难度大。 方案阶段通过风天平对比试验进行了外立面风荷载优化，减小了风荷载输入，使结构体系更加简洁高效。 由于场地岩层较深，卵石层厚达 70m，桩基设计中在当地较早采用了旋挖成孔和 C50 水下混凝土，改进了后注浆技术措施，通过多桩型试桩比选确定了最优桩基础方案，实现了经济性和承载力的合理平衡。 因建筑方案存在单侧退台收进，故对塔楼的水平变形进行了研究，计算分析中考虑了竖向荷载、基础不均匀沉降和混凝土收缩徐变的影响。 结果表明:对于超高层混凝土结构，收缩徐变是需要特别重视的技术环节，考虑基础沉降以后，配筋规律会发生变化。

Abstract: The main tower of the second phase of China Resources Wenzhou laogang district is a 300m high reinforcedconcrete frame￣core tube structure， with steel tube￣reinforced concrete columns at the bottom. The project is located in ahigh wind pressure area along the river， with an aspect ratio close to 7. 5， which makes it difficult to design for windresistance. In the project phase， the wind load on the facade was optimized through the wind balance test， which reducedthe wind load input and made the structural system more concise and efficient. Due to the deep rock layer of the site and thethickness of the pebble layer up to 70m， the pile foundation design adopted the rotary digging hole and C50 underwaterconcrete earlier in the local area， and improved the post￣grouting technical measures. Optimal pile foundation scheme wasdetermined through the comparison and selection of multiple pile types. The optimal pile foundation scheme achieved areasonable balance between economy and bearing capacity. Due to the unilateral retreat of the building plan， the horizontaldeformation of the tower was studied， and the effects of vertical load， uneven foundation settlement， and concrete shrinkageand creep were considered in the calculation and analysis. The results show that for super high￣rise concrete structures，shrinkage and creep is a technical link that needs special attention. After considering the settlement of the foundation， thereinforcement law will change.
