Seismic Performance of a Layered Liquefiable Site: Validation of Numerical Simulations Using Centrifuge Modeling
Effective mitigation of liquefaction requires a reliable evaluation of liquefaction triggering and its consequences in terms of excess pore pressures, accelerations, and displacements. However, reliable prediction of all these key response parameters remains challenging in the past. In this paper, the results of a centrifuge experiment modeling of a layered soil profile, including a liquefiable layer of Ottawa sand, are used to evaluate the predictive capabilities of two state-of-the-art constitutive models. The models were first calibrated using the same set of monotonic and cyclic triaxial tests and were then used to simulate the seismic performance of a layered soil deposit to a horizontal earthquake motion. This paper presents the systematic calibration process adopted for each constitutive model, followed by a comparison of the numerical results with centrifuge recordings. This effort aims to provide insight into the strengths and limitations of the adopted models.
