The expansion of the Port of Long Beach-Pier S, a major U.S. port facility, has been completed through the past decades by placing loose man-made hydraulic fills. These fills and their subjacent natural estuarine and marine deposits, have shown to be susceptible to liquefaction. This case of study is located within a few miles of the Newport-Inglewood and the Palos Verdes faults, which represent a high seismic hazard to the port. In this paper, numerical analyses are performed using the UBC3D-PLM constitutive soil model to determine the onset of liquefaction and estimate free-field ground-induced settlements based on post-liquefaction excess pore water pressure dissipation. It is concluded that this model, even with certain limitations, is able to predict the onset of liquefaction capturing numerous features of dynamic soil behavior, and can be used as a first estimate of liquefaction-induced settlements arising from dissipation of excess pore water pressures.
