ABSTRACT:
A method for controlling deformation of an erected structural metal plate culvert or underpass during backfilling of the erected structure comprises: building progressively a reinforced earth retaining system on each side of the erected structure by alternately layering a plurality of compacted layers of earth with interposed layers of reinforcement to form reinforced earth on each side of the erected structure and securing to each side of the structure each said layer of reinforcement in the reinforced earth, whereby such securement of each said layer of reinforcement to said structure controls deformation of the erected structure during backfilling with the reinforced earth on each side of the structure. The layer of reinforcement may be a plurality of strips extending away from the structure, or a reinforcement mat of interconnected rods.
