Numerical Modeling of Dynamic Consolidation by Blasting Ramming in Soft Clay Foundation

摘要：

A numerical modeling method is proposed for transforming the three-dimensional soft clay treatment by drainage consolidation with explosive vibrations into a two-dimensional plan strain problems. In this method, the sand drains is transformed into equivalent sand walls, and the explosive pressure on porthole is transformed into equivalent pressure walls, which is based on the mechanism of equivalent impulse. The deformation of soil skeleton and the non-Darcy seepage of pore water are coupled in the numerical modeling. A comparison of the numerical results with the in-situ experimental results shows that both results are comparable. The numerical method is capable of modeling the dynamic process of the occurrence and dissipation of excess pore pressure and the soil settlement in the course of the dynamic consolidations.
