摘　　要：通过对挤扩多盘桩国内外研究现状的分析,提出了现有抗拔桩理论的局限性,初步探讨了承力盘参数(盘数、盘间距、径高比等)对挤扩多盘桩抗拔承载力的影响,为进一步确定挤扩多盘桩单桩抗拔承载力计算公式奠定基础。In this paper, it is preliminarily discussed that the influence parameters of the multi-under-reamed of bearing loads （ the quantity,the distance and the ratio between diameter and height of the multi-under-reamed of bearing loads） for the tensile resistance capacity of the pile by the analysis of the international and national research state about the push-extend multi-under-reamed pile, and it provides a theoretical basis for the further definition of the calculation formula of the bearing capacity of the tensile resistance of the push-extend multi-under-reamed pile.
