The authors first proposed the application of the Unit Impulse Load Method to solve the dynamic contact problem in the analysis of foundation treated by heavy tamping method. The three-dimension dynamic finite element program had also been copiled to carry out the dynamic calculation. Compared with the practical engineering data, the calculated results are satisfactory.
Keywords: heavy tamping method; unit impulse; three-dimension finite-element; dynamic calculation
