Abstract : The effect of the environmental pressure on the consolidation and shear strength characteristics of deep ocean soils was investigated. Consolidation, direct shear and vane shear tests were performed on remolded specimens of soils dredged from the ocean bottom. These tests were conducted in sea water within pressure chambers at hydrostatic environmental pressures up to 10,000 psi and at temperatures of 1 to 3C, the temperature of the deep ocean. These tests were conducted on completely remolded deep ocean specimens which had a soil structure different from the in situ structure. Therefore, the results obtained may differ for the same soils in the natural state. (Author)
