Lifting of a large object from a porous seabed

  • Chiang C. Mei (a1), Ronald W. Yeung (a2) and Ko-Fei Liu (a1)

The time required to pull a large object from a sandy seabed is estimated by assuming that the seabed is porous but rigid. The phenomenon of breakout (i.e., sudden release) is shown to occur without the assumption of elasticity of the soil skeleton (Foda 1982). A new case of wedge-shaped gap is also studied, and compared to a uniform gap, Laboratory experiments are shown to support the theory.
