UNAIDED BREAKOUT OF PARTIALLY EMBEDDED OBJECTS FROM COHESIVE SEAFLOOR SOILS

The Naval Civil Engineering Laboratory has conducted field and laboratory tests to investigate the effort required to remove partially embedded objects from cohesive seafloor soils. This work is intended to aid in proper selection of elements for Navy salvage and rescue operations. This report presents the results of the tests and an analysis of the results. Procedures are given for use by field engineers in predicting forces required to remove objects immediately and in estimating time required when lesser forces are applied. The accuracy of the force prediction procedure is about plus or minus 50%; the accuracy of the time prediction procedure is about plus or minus 100%. These accuracies are comparable to those usually attainable with other time-dependent soil mechanics problems and should be acceptable for typical object retrieval operations.
