| 摘 要： | 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.通过与等直径管桩的对比试验,表明静压扩底管桩的承载力明显提高,而沉降变形则要小很多;试验还得到了桩底混凝土扩大头的具体尺寸情况,为静压扩底管桩的工程应用提供了试验依据.

| Abstract: | 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.The construction technique of the expanded-foot tubular pile by static driving method is introduced.In contrast to the equivalent-diameter tubular pile,it can be seen that the bearing capacity of the expanded-foot tubular pile by static driving method is much higher than that of the equivalent-diameter tubular pile,while its settlement is much lower;the test also obtain the dimension of expanded-foot.The achieved results of the model test provide data for engineering application of the expanded-foot tubular pile by static driving method. |
