The pressures generated during large earthquake shaking can cause the liquefied soil and excess water to force its way to the ground surface. Soil particles can no longer support all the weight of overlying civil infrastructures. Bridges and large buildings constructed on pile foundations may lose support from the adjacent soil and come to rest at a tilt after shaking. To represent the non-linear and complex nature of pore pressure buildup with in the soil mass, efficient constitutive models are developed. One of such model is UBC SAND and it has well validated with experimental data in the previous research publications. Hence the present paper has focused to analyses the pore pressure buildup of foundation soil for bridge abutment by using UBC-SAND constitutive soil model into the finite element GT software. The results are displayed in the form of graphical output. UBC sand model addresses the pore pressure ratios at different levels of soil profile.
