Abstract:In the process of dynamic compaction, large deformation occurs at some rammed points and their surrounding areas. In this paper, the vibration of dynamic compaction is analyzed with the large deformation theory and LS-DYNA finite element software is employed to simulation the process of dynamic compaction. The velocity-time data acquired in the analysis are close to the actual data measured in dynamic compaction. Using dimension analyzing method reasons a relational formula between vibration velocity and weight of the hammer. And the author uses the actual measured data to imitate the relationship of the vibration velocity. The formula provides a new method to forecast the vibration of dynamic compaction, which makes sense for the similar construction work to forecast the impact for adjacent buildings.
