AB - Ground settlement is one of the main consequences of liquefaction and can develop during seismic shaking, as well as for a period after the end of the strong motion. In the post-shaking phase, once the seismic shaking ceases, water continues to flow upwards towards the surface, with ground settlement evolving until the excess pore water pressure is completely dissipated within the soil deposit. This process, known as post-liquefaction reconsolidation or simply reconsolidation, results in volumetric strains and settlements, which are challenging to model numerically using conventional constitutive frameworks for sands as loading under constant stress-ratio is often not captured accurately. In this study, a modified bounding surface plasticity model employing fourdifferent elastic stiffness constitutive relationships is proposed to improve the accuracy of simulating post-liquefaction reconsolidation.Fully coupled dynamic consolidation finite element analyses of level ground deposits subjected to seismic loading are conducted,illustrating the impact of the new formulation in terms of excess pore pressure dissipation and ground settlement evolution.
