摘　　要：通过建立桩-土共同作用的有限元模型,分析了挤扩多盘桩的承力盘问距对单桩抗拔承载力的影响,并提出合理的承力盘间距,为挤扩多盘桩抗拔理论进一步完善提供了借鉴。In this paper, it is analysed the influence about the distance between the bearing push-extend reamed for the bear- ing capacity of the tensile resistence of the Push-extend Multi-under-reamed Pile by building the finite unit model of pile and soil work together, and it is deduced the reasonable distance between the bearing push-extend reamed, that provides experiences and lessons for the theory of the bearing capacity of the tensile resistence of the Push- extend Multi-under-reamed Pile.
