摘要
总结了复合模量计算的研究现状;提出了考虑群桩间相互影响的复合地基模量计算公式,即由于邻桩对桩间土的加固作用而使复合模量比单桩模型的计算值有所增加;公式同时考虑了沉桩对桩间土模量的提高作用。最后通过算例验证了所提出的公式。
The status quo of research on calculating modulus of composite foundation was summarized in this paper.A formula for calculating modulus of composite foundation was put forward and verified through a case.Interactions of piles,influence of pile-sinking on soils were taken into account in the formula.Because of considering the reinforcement of neighboring piles,modulus of composite foundation calculated by the formula in this paper is bigger than that by model of single pile.
