Earthquake-Induced Ground Settlements of Bridge Abutment Fills
Simplified methods of analysis are herein proposed for estimating earthquake-induced abutment fill settlements. Primary factors such as excitation history, amplification (or deamplification) within the fill, and nonlinear soil properties and slope geometry which control the settlement have been accounted for in the approach. Settlement caused by the permanent slope rotation has been obtained from a procedure similar to Newmark's sliding block model. Additional settlement caused by grainslip-induced deformation is also incorporated. Readily usable simple relationships have been developed based on the extensive seismic excitation database generated from the 1994 Northridge earthquake in order to evaluate settlements of typical abutment fill heights of 4–10 m subjected to any earthquake excitation.
