摘要： 针对软土地基，通过有限元分析软件ABAQUS，模拟强夯加固软土地基的过程，分析了在相同夯击能不同落距和夯锤质量作用下，土体的应力及竖向位移，比较准确的模拟了强夯在加固软土地基上的应力及位移变化，对以后类似的强夯加固软土工程有一定的参考。

Abstract: Numerical analysis was performed to simulate the process of dynamic compaction on soft soil foundation.  The analysis studied the effect of different combinations of drop height and ram while maintaining the same impact energy. Stress and displacement of the soft soil foundation during dynamic compaction can be accurately predicted using numerical analysis.
