Dynamic compaction replacement is a method used to reinforce the full soft clay foundation. The reinforcement mechanism of dynamic compaction replacement method is different from that of dynamic compaction method. It uses the high impact caused by the high drop of heavy hammer to force the gravel, rubble, slag and other materials with good functions into the foundation to form one by one granular material pier in the foundation, and the soil between the piers forms the composite foundation, so as to improve the bearing capacity of the foundation and reduce the settlement. In the process of dynamic compaction replacement, the soil structure is damaged and excess pore water pressure occurs in the foundation soil. However, with the time increasing, the strength of soil structure will be recovered. Generally, the granular pier has good water permeability, which is conducive to the dissipation of excess pore water pressure and consolidation.
