Abstract
A method for controlling deformation of a cut end region of an erected arch-type structure for use in underpass construction and the like where the cut end region has at least one extended leg portion. The method comprises building progressively at least one layer of mechanically-stabilized earth adjacent the extended leg portion by alternately layering a plurality of compacted layers of fill with interposed layers of reinforcement. Each layer of reinforcement is secured to the extended leg portion during the progressive building. The securement of the layers of reinforcement to the extended leg portions provide support in controlling deformation of the cut end region during backfilling and regular service.
