摘　　要：应用简单的弹塑性动力计算模型对冲击压实技术在软粘土地基加固中的作用机理进行数值模拟,预测软粘土地基在冲击压实荷载作用下的动力响应。结合实际工程给出了在考虑地基材料的剪切模量、阻尼比等因素情况下的计算结果。This paper carries out numerical simulation for the mechanism of impact compaction technology in soft clay foundation reinforcement with simple elastic plasticity dynamic calculation model and also predicts dynamic response of soft clay foundation under the effect of impact compaction load. It gives calculation result considering shear modulus and damping ratio of foundation materials combined with practical engineering.
