Abstract:

A 146-acre dredge spoil disposal facility was constructed in Baltimore Harbor that received 3. 4 million cubic yards (2. 6 million cubic meters) of dredge spoil generated from construction of the Fort McHenry tunnel. Consolidation of compressible soils underlying the site and consolidation of the dredge spoil during disposal were included in estimating the maximum available capacity. The actual capacity was appraised during dredging by field surveys and soundings. Disposal procedures were modified to compensate the capacity shortfall projected.
