It is generally considered that the saturated soft clay foundation should not or should be cautiously strengthened by dynamic compaction method.The growth and dissipation of pore pressure under impact load is the basic and theoretical support for the study of dynamic consolidation method for saturated soft clay foundation. One-dimensional model test of pore pressure growth and dissipation of saturated soft clay under impact load is obtained from the perspective of experiment and preliminary mechanism analysis, and the effects of different number of shots N and different impact energy WH are obtained in the experiment Some useful results
