• Abstract:
  This study investigates the shear tendencies of soft sediments from the New York and New Jersey harbor under direct simple shear loading conditions experimentally and numerically. Four sediments were stabilized with Portland cement and subjected to direct simple shear loading with varying confining pressures and curing durations to elucidate the impact on the stress-strain responses and stress paths. Additionally, unconfined compressive strength (UCS) tests were performed to provide a baseline for comparing the DSS results with methods commonly used in practice. Following the lab testing, the experimental results were used to calibrate numerical models using the Mohr-Coulomb and PM4Silt (Ziotopoulou and Boulanger 2019) constitutive models to evaluate the potential of accurately simulating the deformation tendencies and providing methods for system level modeling of structures constructed with stabilized sediments. The findings of this research may open new avenues for incorporating stabilized sediments into projects with more rigorous design criteria; however, further work is required to utilize these results in practice.
