摘　　要：某港口工程为填海回填土地基,地层土质复杂且不均匀。针对复杂且软弱的回填土地基,为验证强夯处理加固效果与优化强夯施工参数,采用2500 kJ的夯击能,通过多区试夯、多遍点夯、设置最大夯击数、复夯及保险性碾压等技术措施对地基进行加固。经静荷载板试验等方法对夯前夯后场地地基进行分析评价,强夯法能使回填土地基达到加固设计要求。A port engineering involves land reclamation with backfill soil foundation,where soil layers are complex and uneven.In response to the complex and weak backfill foundation,in order to verify the reinforcement effect of dynamic compaction treatment and optimize the dynamic compaction construction parameters,we use a compaction energy of 2500 kJ,and apply technical measures to reinforce the foundation,such as multi-zone test compaction,multiple point compaction,setting the maximum number of compaction blows,repeated compaction,and ensuring rolling.Then we analyze and evaluate the foundation before and after compaction by test method such as static load plate test.The dynamic compaction method can make the backfill soil foundation meet design requirements for reinforcement.
