桩筏基础由于其整体性好、竖向承载力高、基础沉降小、调节不均匀沉降能力强等优点,日益成为高层建筑普遍采用的一种重要的基础形式。本文从从群桩的共同作用影响、高层建筑上部结构与地基与基础的共同作用几个方面简要分析了高层建筑桩筏基础共同作用机理。 Because of its good integrity, high vertical bearing capacity, small settlement of foundation and uneven settlement ability, piled raft foundation is increasingly becoming an important basic form for high-rise buildings. This paper briefly analyzes the interaction mechanism of piled raft foundations in high-rise buildings from several aspects, including the interaction of pile groups, the interaction between the superstructure of tall buildings and foundation and foundation.
