Abstract
The creation of dynamic replacement stone columns is a poorly understood process that is difficult to model numerically due to very large displacements and the complex interactions between the soil and the forming stone column. In this paper the authors use the material point method to approximate a well-documented experiment of the creation of a small scale dynamic replacement soil column. In this experiment the column has been formed in a transparent container (66x60x12 cm) filled with sawdust. The material point simulation aims to replicate the dynamic replacement experiment using basic constitutive models. The computational results are compared with those obtained in the experiment.
