ABSTRACT

The deformation and magnitude of the coefficient of earth pressure at locations in a Geosynthetic Reinforced Soil – Integrated Bridge System subjected to self-weight and external vertical and horizontal loads was investigated using Plaxis 2D. The soil mass was found to move outward at all locations under all loading conditions. The application of the external loads increased the outward movement over the full height of the wall. The magnitude of the coefficient of earth pressure varied significantly. Over the middle two-thirds of the wall height the coefficient was close to the active value or between the active and at rest values. At the top and bottom of the wall it was closer to the at rest value. Directly beneath the bank seat the application of the external loads significantly increased the magnitude of the coefficient to higher than the at rest condition.
