摘　　要：介绍了强夯法加固围垦滩地饱和粉土的机理和工艺,分析了经过强夯法加固前后地基的特性变化。通过现场检测结果,反映强夯后地基一定深度内土体得到有效加固,同时在表层形成了承载力较高的硬壳层。The dynamic compaction strengthening on saturated silt of reclaimed foreland soft ground is introduced including its mechanism and technology.The foundation characteristics changes before and after the dynamic compaction are presented.Through a field test,the results show that the soil body under a certain depth can be strengthened effectively and a crust can be formed on the surface layer with relative high bearing capacity at the meantime.
