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.
