3D Modeling of Pile-Supported Wharf Subjected to Liquefaction-Induced Lateral Ground Deformations
Publication: Geo-Congress 2023
ABSTRACT
A three-dimensional (3D) nonlinear dynamic model of a pile-supported wharf created in FLAC3D was calibrated using data from a centrifuge test in prototype scale. Piles in the test and numerical model were subjected to the combined effects of inertial loads from the superstructure mass and kinematic loads from liquefaction-induced ground deformations during earthquakes. The recently developed pressure-dependent multi-yield surface (PDMY03) constitutive model was used to simulate undrained cyclic behavior of sands with different relative densities and the rockfill. The objective of the numerical modeling was to evaluate the capabilities and limitations of PDMY03 in capturing key dynamic responses of liquefied soils in 3D as well as soil–structure–foundation interaction between the wharf and the laterally spreading ground.
