摘要
在大量实测研究结果的基础上 ,假定复合地基桩间土和桩的接触应力按抛物线模式分布 ,通过地基与结构共同作用条件的满足来确定复合地基的接触应力的具体分布 ,使考虑共同作用的沉降计算成为可能 ,并对最大沉降和差异沉降受结构对地基的相对刚度的影响规律进行分析 ,得出若干有益的结论。
Based on large quantity of observed results,the contact pressure on soil between piles and the contact pressure on piles are assumed to distribute in a parabolic form.The contact pressure of composite foundation is determined by meeting the interaction conditions between composite foundation,foundation and structure,which makes it impossible to calculate settlement considering the interaction.The effects of relative stiffness of the foundation and structure to that of the composite foundation on maximal settlement and differential settlement are analyzed,and the solutions are given.
