Numerical Assessment of Liquefaction-induced Ground Deformations and Loading Mechanisms
Current techniques for the assessment of liquefaction and lateral spreading consequences are based on analytical simplifications and idealizations that potentially result in widespread variation in lateral spread displacement demands. This high uncertainty has resulted in significant additional expense and/or disruption of bridge design/construction schedules. Salient features of the commonly encountered stratified site conditions need to be addressed using effective stress site response analyses. Of particular concern is the uncertainty in determining the extent of liquefiable soil or the particular soil stratum contributing to the dominant lateral spread zone during an earthquake. This can best be determined using effective stress site response analysis to establish zones or strata first triggering liquefaction, and then determine the associated ground deformations.
