摘要
本文介绍对黑龙江省金融大厦首次采用以粗砂为持力层的扩底桩基础设计以及扩底桩基础与地基相互作用的空间体系电算分析,给出桩底反力分布、基础变形、地基与承台结构刚度的影响等结果.
This paper discribes the design of the pedestal pile foundation of Heilongjiangprovincial Financial Building,with the first use of coarse sand layer as bearing stra-tum,and the analysis in three dimensions of the interaction between subsoil andpedestal pile foundation.The distribution of the reaction at the bottom of piles,thedeformation of the foundation,the effect of subsoil deformation modulus and rigidityof pile copping structure are discussed in this paper.
