According to the actual behaviour of the expanded-foot tubular pile by static driving method,a model test equipment had been designed to study bearing capacity,settlement and the shape of expanded-foot of the expanded-foot tubular pile by static driving method.

结合静压扩底管桩工程应用情况,设计了一个室内模型试验装置来研究静压扩底管桩的承载力、沉降变形性能及扩大头成形情况,并介绍了静压扩底管桩的施工工艺。

Expanded-foot tubular pile by static pressure method is composed ofprestressed concrete tubular pile and expanded-foot.

静压扩底管桩是由预应力混凝土管桩和其下部的混凝土扩大头两部分组成，该桩型利用管桩空心的特点，加压一部分混凝土至桩底形成扩大头，它在力学上兼具预制桩和夯扩桩的优点，不存在断桩和缩颈现象，具有承载力高、沉降变形小等特点，非常适合在软土地区应用，具有广阔的应用前景和良好的经济效益。
