| Abstract: | Based on field test，laboratory soil test and post-construction settlement monitoring and combined with theoretical and numerical analysis，the effect of dynamic compaction on widened subgrade reinforcement and differential settlement reduction is studied.As a result，the subgrade reinforced by dynamic compaction and settled by 0.245 m on an average and the consolidation degree of the foundation soil reached 57 %.Therefore，the settlement of both the new and old subgrade has met the specification. |

| Keywords: | dynamic compaction foundation widened subgrade differential settlement post-construction settlement |
