This invention relates to a novel design of reinforced soil arch which can
be used to construct bridges, overpasses, snowsheds, landslide or rock
fall protection structures, and the like. More particularly, this
invention pertains to an innovative use of mineral soil (clay, silt, sand,
gravel, cobbles, boulders, broken rock or mixtures of any or all of the
foregoing) to construct a reinforced soil arch that can be used for
numerous purposes. A method of constructing a reinforced soil arch
comprising constructing an arch utilizing a combination of layers of
compacted mineral soil and reinforcement in a manner that supports both
the dead load of the structure and a live load imposed on the structure.
