BREAKOUT RESISTANCE OF OBJECTS EMBEDDED IN OCEAN BOTTOM

Abstract

A study is made of factors that affect the magnitude of breakout resistance of objects embedded in the ocean bottom. Following a literature review most discussions deal with the basic problem of a centrally loaded object pulled by vertical force from a sediment with level surface. Considerations of effects of eccentric and inclined loading and slope of the ocean bottom are added. It is found that failure patterns depend on relative depth of the object, as well as on soil type. Theoretical analyses show better agreement in soft and loose soils than in stiff and dense soils. Suggestions for analysis of suction force and effects of soil liquidity are given. Recommendations for future research include four problem areas: (1) Effects of soil liquidity and compressibility on failure patterns; (2) adhesion between soil and buried objects; (3) nature and magnitude of suction force; (4) rheological properties of soils in breakout.
