Method for determining tamping settlement and optimal tamping frequency in dynamic compaction process
The application discloses a method for determining the tamping settlement and the optimal tamping frequency in the dynamic compaction process, and relates to the related technical field of civil engineering foundation treatment. The method for determining the tamping settlement in the dynamic compaction process comprises the steps: dividing the dynamic compaction process into an impact loading stage and an unloading springback stage; establishing a rammer displacement time-history equation in the impact loading stage to obtain the displacement of the rammer in the impact loading stage; establishing a rammer displacement time-history equation in the unloading springback stage to obtain springback displacement of the rammer in the unloading springback stage; and subtracting the rebound displacement of the rammer in the unloading rebound stage from the displacement of the rammer in the impact loading stage to calculate the tamping settlement in the dynamic compaction process. According tothe application, rammer displacement time-history equations of the impact loading stage and the unloading springback stage are respectively established; the tamping settlement of the dynamic compaction process is calculated according to the rammer displacement time-history equation, a theoretical basis is provided for determination of the tamping settlement, the tamping settlement of the dynamiccompaction process can be calculated, and the optimal compaction frequency of the dynamic compaction process is further judged according to the tamping settlement.
