N2 - This paper summarizes the results of an experimental study directed towards the validation of a mathematical model for the buildup of pore water pressure and resulting liquefaction of marine soils under progressive waves. Experiments were conducted under controlled conditions with silt (d(50) = 0.070 mm) in a wave flume with a soil pit. Waves with wave heights in the range of 7.7-18 cm, 55-cm water depth and 1.6-s wave period enabled us to study both the liquefaction and no-liquefaction regime pore water pressure buildup. The experimental data were used to validate the model. A numerical example is also included in the paper to demonstrate the implementation of the model for real-life scenarios.
