Abstract

A new flexible three-dimensional numerical pore pressure model is developed and used to assess the liquefaction potential at a field site susceptible to scour. The model is tested against a more complex analytical solution and found to give good results. The field test shows that partial saturation has a significant effect on liquefaction potential and that failure depths are similar to erosion depths reported at the site. 1 Introduction Determination of pore pressure under wave conditions is an increasingly important aspect of seabed stability analysis in offshore engineering. Phenomena such as wave-induced liquefaction should be accounted for, especially where enhanced wave conditions exist as in the vicinity of marine structures. Vario
