WAVE-INDUCED PORE PRESSURE ACTING ON A BURIED SUBMARINE PIPELINE

Waldemar Magda

Abstract


The response of a sandy seabed to surface water waves, with a special emphasis to wave-induced excess pore water pressure oscillations is studied here in relation to the vertical stability of submarine buried pipelines. The main object of the peper is to present a study of the distribution patern of the pore water pressure acting around the pipeline, and to calculate the seepage force, the up-lift force particularly, affecting the pipelne stability, under the assumption of compressible both the pore fluid and soil skeleton, for the case of an arbitrary seabed depth as well as for the infinite thickness of the subsoil.
