Geotechnical properties of sediments from North Pacific and Northern Bermuda Rise
Studies of geotechnical properties for the Sub-seabed Disposal Program have been oriented toward sediment characterization related to effectiveness as a containment media and determination of detailed engineering behavior. Consolidation tests of the deeper samples in the North Pacific clays indicate that the sediment column is normally consolidated. The in-situ coefficient of permeability (k) within the cored depth of 25 meters is relatively constant at 10/sup -7/ cm/sec. Consolidated undrained (CIU) triaxial tests indicate stress-strain properties characteristic of saturated clays with effective angles of friction of 35/sup 0/ for smectite and 31/sup 0/ for illite. These results are being used in computer modeling efforts. Some general geotechnical property data from the Bermuda Rise are also discussed.
