Vibro stone columns are widely used worldwide for the improvement of soft foundations. The characteristics of underground engineering make it almost impossible to perceive the morphology of columns, and the prediction of the morphology of columns formation is also relatively preliminary. A simulation method for the formation of vibro stone columns based on real construction data is proposed. The construction process parameters are extracted from monitoring data and then transferred to simulation parameters. Based on the coupled Eulerian–Lagrangian method, parametric modeling techniques, and script-based post-processing techniques are used to implement the simulation of continuous construction processes. The formation mechanism of vibro stone columns is analyzed based on the formation process simulation. This method can be used for quality evaluation and digital twin of vibro stone columns.
