| Description: | Miscellaneous Paper Abstract: The fixed-weir portion of the Newburgh Lock and Dam project is to be constructed of concrete-capped cofferdam cells. These cells are to be filled with a cohesionless foundation material which is a poorly graded, gravelly sand (SP-SM) with about 5 percent nonplastic fines. Because the site is in a seismic zone 3 (Algermissen), a laboratory study was conducted to evaluate the earthquake response of the gravelly sand at various densities. About 60 lb of the material was obtained from the Louisville District, and cyclic triaxial compression tests were conducted on the sand compacted to nominal 40, 60, and 80 percent relative densities. Based on the results of these tests, it appears that an in-place relative density of at least 75 percent is desirable. Therefore, it is expected that some means of underwater compaction will be required. |
