摘要
对夯扩桩扩大头的形成机理和形状进行了分析与探讨 ,提出了夯扩变形影响半径、桩端承载力计算的经验公式。理论分析结果与室内模型试验结果吻合较好 ,为夯扩桩的设计计算提供了依据。
Based on the model tests of rammed pedestal pile carried out in laboratory,the head-expanding mechanism is proposed and analysed qualitatively,and the empirical formulas of ramming effect radius and end bearing capacity are also deduced.The theoretical analysis agrees with the experimental data,and thus providing the basis for the design and calculation of the rammed pedestal pile.
