摘　　要：在挤扩多盘桩现有的研究成果的基础上,通过半面桩小模型原状土试验,研究了竖向拉力作用下,挤扩多盘桩的盘间距对桩周土体破坏机理的影响,明确了合理的盘间距取值,为竖向拉力作用下挤扩多盘桩的承载力计算及工程设计提供了可靠的理论依据。On the base of the existing achievements of the MEEP pile, the article through the small model pile with self-section test of undis-turbed soil, indicates the effect of plate space of the MEEP pile on the uplift failure mechanism of the soil surroundings pile, which will provide a reliable theoretical basis for engineering design and calculation of the uplift bearing capacity of the MEEP pile.
