Abstract:This research studied numerically the detrimental effects of liquefaction-induced ground movements during a seismic event at the Port of Long Beach, which is vital for the California freight network. The research included: i) the calibration of constitutive model parameters after a compilation of published subsurface investigation reports of the POLB and to determine the suitability of these parameters to reproduce laboratory tests following different stress paths and shear strain levels; ii) the assessment of the use of advanced constitutive models like the UBC3D-PLM to predict the behavior of the POLB Pier S when a seismic event induces liquefaction; iii) the recommendations regarding the resulting permanent deformations and residual strength of soils which could compromise the resiliency of the port.
