强夯法是深层密实法的一种，是一种将几十吨的重锤，从几十米的高空落下，对土进行强力夯击的方法。

Dynamic compaction is a kind of deep compaction, it is a kind of method that tens tons of heavy hammers from tens of metres to consolidate soil.

本文采用动力接触有限元法分析了强夯对地基土的冲击碰撞过程。夯击过程中，夯点周边地基土存在局部大变形现象。

This paper uses dynamic contact FEM to analyze impact and collision course of dynamic compaction to foundation soil.
