摘要
某超高层建筑高243 m,主体结构采用了框架-核心筒结构体系,基础选用桩筏基础形式。该工程主楼、裙房、纯地下室地下连为一体,形成大底盘主、裙地下连体建筑基础。为有效控制差异沉降,采用了变刚度调平设计、灌注桩后注浆和设置后浇带等有效措施。在简要介绍该工程结构特点的基础上,系统地阐述该工程基于结构布置、地质情况等因素综合考虑进行的基础设计,重点介绍变刚度调平设计的方法。
A super high-rise building was located in Jiangyin with a height of 243 m. It was adopted the frame- corewall structural system and pile raft foundation. The main building, podium and pure basement were connected together underground without any deformation joint, which leaded to an enlarged base. Therefore, optimized design of pile foundation stiffness, post grouting for cast-in-situ pile and post-pouring belt were used in the project for controlling differential settlement. The structure characteristics were briefly introduced, where the foundation design based on the structural arrangement and geological data were elaborated. An optimized design of pile foundation stiffness to reduce differential settlement was emphatically introduced.
