Zusammenfassung:	The application discloses a method for controlling a dynamic compaction process by measuring compaction settlement therein and a method for optimum compaction time, and relates to the technical field related to the foundation treatment of civil engineering. The method for determining the compaction settlement in the dynamic compaction process comprises the steps of diViding the dynamic compaction process into an impact loading stage and an unloading rebounding stage; establishing a time history equation of rammer displacement in the impact loading stage to obtain rammer displacement in the impact loading stage; establishing a time history equation of rammer displacement in the unloading rebounding stage to obtain the rebounding displacement of the rammer in the unloading rebounding stage; and subtracting the rebounding displacement of the rammer in the unloading rebounding stage from the rammer displacement in the impact loading stage to calculate the compaction settlement in the dynamic compaction process. According to the application; the compaction settlement in the dynamic compaction process can be calculated; and the optimum compaction time in the dynamic compaction process can be further judged according to the compaction settlement.
