On settlement analysis of soft-soil foundation after impact compaction

The paper adopts the impact compaction method to treat the soft-soil foundation,inspects the settlement during the engineering period of the foundation after the treatment,predicts the settlement after the construction by adopting the Poisson curve method,compares it with the calculation results by the layer settlement accumulation method,and proves by the results that the left settlement of the foundation after the impact compaction is about 7.9% ~11.6% of the total settlement of the foundation,so the settlement of the foundation is reduced by 36%,and indicates the effect of the treatment for the soft-soil foundation is better,so it can ensure the stability of the foundation.
