Abstract
Soil liquefaction presents a significant hazard to the built environment. The seismically induced permanent displacement of earth levees, dams, and embankments resulting from liquefaction below these earth structures is not well captured in current seismic design practice. The objective of this study is to advance the capabilities of numerical methods toward the solution of problems involving limited lateral spreads. The nonlinear soil constitutive model UBCSAND, as implemented in the finite difference program FLAC, (Itasca), is used to evaluate the seismic deformations of the newly-constructed Moss Landing Marine Laboratory (MLML) in Moss Landing, California resulting from liquefaction-induced lateral movements during the Loma Prieta earthquake of 1989. A material parameter selection protocol was developed through one-element modeling of laboratory testing and then implemented to predict deformations at the MLML facility.

Calibration of Numerical Model for Liquefaction-Induced Effects on Levees and Embankments

Soil liquefaction presents a significant hazard to the built environment. The seismically induced permanent displacement of earth levees, dams, and embankments resulting from liquefaction below these earth structures is not well captured in current seismic design practice.

The nonlinear soil constitutive model UBCSAND, as implemented in the finite difference program FLAC, (Itasca), is used to evaluate the seismic deformations of the newly-constructed Moss Landing Marine Laboratory (MLML) in Moss Landing, California resulting from liquefaction-induced lateral movements during the Loma Prieta earthquake of 1989.
