Abstract : Construction of earth embankments on soft foundations is often a difficult geotechnical engineering problem. Construction of a proposed confined dredged material disposal area for Mobile Harbor, Alabama, requires the U.S. Army Engineer District, Mobile, to construct approximately 5000 linear feet of eight foot high embankments on extremely soft cohesive foundation soils, with undrained shear strength from 50 to 150 p.s.f. The initial embankment would have to provide a stable base for raising an additional 17 feet, and future raising an additional 25 feet. Fine, poorly gradded sand was available nearby for use as borrow material in construction of the initial embankment. It was determined that the most cost-effective and potentially acceptable solution would be to construct civil engineerinfg fabric-reinforced dikes along the proposed alignment. The civil engineering fabric would be placed between the soft cohesive foundation and the sand embankment material in long, narrow strips perpendicular to the alignment, with the strips overlapped and sewn together.
