摘　　要：在强夯法加固地基的分析中,首次提出了采用单位脉冲荷载法来解决动力接触问题,并编制了三维有限元程序进行动力计算.经与实际工程资料对比,计算结果比较令人满意.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.
