Soil-Bridge Abutment Interaction, Bobby W. Meade, David L. Allen

Kentucky Transportation Center Research Report

Presented herein are analyses of 6 bridge approaches. Lateral movement and settlement of the foundations and embankments are discussed. Result·s of slope stability and finite element analyses are related to measured movements. A graph for predicting approach pavement settlement is included. A theoretical approach model was used to run an extensive series of finite element analyses. Movements resulting from these analyses are presented with several variable model conditions. Variable conditions include embankment and foundation configuration, soil cohesion, and soil friction angle.
