Load Reduction by Geofoam for Culvert Extension: Numerical Analysis
Widening of a highway embankment may increase loads acting on the weaker portions of the culvert. To accommodate increased loading, geofoam will be placed above the weaker portions of the culvert. Numerical analysis using FLAC was performed to predict loads on the culvert. Results of the analysis show that geofoam significantly reduces maximum moments on top and bottom of the culvert. The moment reduction is a function of the size of geofoam and the distance between top of culvert and the geofoam. By considering these factors, effectual curves are obtained from the numerical analysis.
