Geotechnical properties of sediments from North Pacific and Northern Bermuda Rise

PDF Version Also Available for Download.

Description

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 ... continued below

These results are being used in computer modeling efforts. Some general geotechnical property data from the Bermuda Rise are also discussed.
