Design of Reinforced Embankments. Executive Summary
A study was made of reinforced embankments constructed on undrained soft foundations using the finite element (FE) method with a cap elastic-plastic work hardening soil behavior model. A straightforward procedure was developed to obtain the cap input parameters from standard soil test results. The FE analyses showed that crust strength and foundation compressibility have the greatest influence on the benefit possible with reinforcement. The main effect of the reinforcement is to reduce shear stresses in the foundation near the embankment toe. Reinforcement was found to be very beneficial for widening and raising the grade of existing embankments. Underlying assumptions of modified limiting equilibrium methods were examined. In addition, a thorough summary of reinforced embankment case histories was presented and evaluated.
