Abstract : A device was developed by the Naval Civil Engineering Laboratory to determine the short-term, in-situ bearing pressure and settlement response of marine sediments at any ocean depth. Tests were performed in cohesive sediments with both round and square bearing plates at ocean depths of 1,200 and 6,000 feet. During a typical test, measurement of load, settlement, and attitude of the device were transmitted acoustically to a surface vessel where they were monitored and recorded. The results of these plate bearing tests were found to be amenable to analysis by modified elastic and bearing capacity theory. A tentative procedure for predicting the short-term settlement of seafloor footings using the results of laboratory tests on core samples was developed on the basis of these two approaches. (Author)
