【 摘 要 】

An analytical formulation is presented for the analysis of the breakout of a half-buried submarine pipe due to wave action. The formulation accounts for the contact between the pipe and the soil due to the horizontal hydrodynamic force. An asymmetric gap geometry is described that incorporates a second order expansion in the gap opening due to the pipe rise. Results with this formulation demonstrate the existence of an initial gap of the order 1 mm in the breakout experiments. With this initial gap, the gap flux dominated the influx of water into the gap from the beginning of the breakout process.
