摘　　要：近几年国内强夯和强夯置换技术越来越多地应用于地基处理工程中,且有向高能级发展的趋势。本文研究辽宁省某碎石土填海地基处理中10000kN·m能级强夯、10000kN·m能级强夯置换、12000kN·m能级强夯以及15000kN·m能级强夯等地基处理施工过程和地基处理效果,提出在碎石土填海地区高能级强夯和强夯置换适宜的主夯点间距和单点夯击次数,以及地基处理效果,以期为类似工程提供相关经验。In recent years,dynamic compaction and dynamic compaction replacement technology have been increasingly applied in foundation treatment engineering in China,and there is a trend towards high-energy level development.This article studies the construction process and foundation treatment effect of 10000kN·m level dynamic compaction,10000kN·m level dynamic compaction replacement,12000kN·m level dynamic compaction,and 15000kN·m level dynamic compaction in a certain gravel soil reclamation foundation treatment in Liaoning Province.It proposes the appropriate main compaction point spacing and single point compaction frequency for high-energy level dynamic compaction and dynamic compaction replacement in the gravel soil reclamation area,as well as the foundation treatment effect,in order to provide relevant experience for similar projects.
