超高层建筑的基础桩承载性能研究及环境效应分析

Research on bearing capacity of pile foundation and analysis of environmental effect for skyscraper

以我国某超高层建筑桩基础工程为例,通过桩基础现场试验,利用Q-S曲线及桩身轴力分布对超长大直径灌注桩的承载性能进行研究,得到超长大直径灌注桩沉降及轴力传递特性。同时,作者还对超高层建筑的环境效应进行分析,认为应从地面沉降和边坡变形两个方面进行考虑。

Taking pile foundation of some skyscraper as an example,settlement and axial-stress character of super-long and large-diameter bored pile can be concluded by Q-S curve and axial-stress distribution obtaining from field test of pile foundation.At the same time,author consider that environmental effect of skyscraper can be analyzed from settlement of ground and deformation of side slope.
