Aiming at the problems of selecting design parameters of dynamic compaction and monitoring of dynamic compaction construction in overseas port construction projects,this paper compares and analyzes in detail the Chinese,European and American codes and the manual of dynamic compaction suitable improvement soil,design parameters and construction monitoring.By comparison,it is found that the biggest difference among Chinese,European and American codes and manuals on dynamic compaction method lies in the design concept.Energy method is widely used to design construction parameters in Europe and America,while in China,the selection of construction parameters is guided by the reinforcement effect after dynamic compaction.
