摘要
根据强夯加固地基与室内击实试验的相似之处,用室内击实试验探讨了强夯加固地基中硬壳层的形成机理,得出为了使强夯中得到比较密实的"硬壳层",夯击过程应该使用先轻锤后重锤的夯击方法,同时应该分多遍来夯击的结论。
According to the similar aspects between consolidating by forced tamping foundation and laboratory compaction test, by using laboratory compaction test the author discusses the formation mechanism of hard shell in consolidating by forced tamping foundation, obtains the conclusion that in order to get more compacting “hard shell” in dynamic compaction, the process of ramming impact should use the method of light hammer first and heavy hammer second, and getting ramming impact division multiple times.
