| 摘 要： | 夯扩桩室内模型试验的扩大头高度与规范推荐公式的计算结果存在差异，二个实际工程的现场原型试验桩样本实测结果进一步证实规范公式存在缺陷．本文从扩大头的形成机理出发，认识产生这种差异的内在规律．

| Abstract: | Difference exists in the base height of rammed enlarged piles between the model test and the calculated test. The calculation is further proved to be faulty by two site tests. Based on the formation mechanism of the base of rammed enlarged piles, the internal principle which gives rise to this difference is pointed out. |
