Abstract

The study attempts to replicate vibration data caused by dynamic compaction with the Generalized Interpolation Material Point Method. The paper simulates dynamic compaction based on data from a case study from Gdańsk, Poland. We used the Mohr-Coulomb constitutive model with manually adjusted stiffness to account for the nonlinear small-strain stiffness of soil. The findings reveal errors ranging from 0% to approximately 50% in maximum vertical acceleration compared to measurements. However, the peak vertical velocities align well with empirical estimates and Finite Element Method simulations. These results highlight the potential of the Material Point Method for vibration analysis while underlining the need for further refinement to enhance accuracy.
