Abstract:
1. A system for repair or reconstruction of a subsurface support of an overlying manmade construction, said subsurface support including an abutment with at least one wall, said system comprising: geosynthetically confined soils installed within an excavated area adjacent to the subsurface support; a plurality of first soil nails emplaced through the at least one wall, and below the geosynthetically confined soils, said soil nails being employed at an angle, including a horizontal component; said geosynthetically confined soils include at least two sections, each section having a different density defined by selected aggregate and/or soil that fills the gaps between the layers of sheet material, a first section of said at least two sections is located beneath said manmade construction, and a second section of said at least two sections is located adjacent to the first section, said geosynthetically confined soils having a lateral extension that extends at least a ratio of 0.70 with respect to a height of the subsurface support; and a plurality of second soil nails emplaced substantially vertically through a base of the abutment.
