Theoretical Analysis of Model Seabed Behavior under Water Wave Excitation

TLDR: Theoretical analysis of the behavior of a model seabed subjected to water wave excitation is presented in this article, which is based on the classical soil mechanics, including the Biot type approach.

Abstract: Abstract Theoretical analysis of the behavior of a model seabed subjected to water wave excitation is presented. The experiments were performed in the wave flume at the Danish Technological University in Lyngby. Such experiments are unique in engineering sciences and therefore provide unique empirical data for testing various models of the seabed. A controversial explanation of the experiments is presented in the literature. The goal of this research was to study pore pressure changes caused by water waves and the subsequent liquefaction of the seabed. The authors of the present contribution offer their own theoretical explanation of the wave flume experiments and discuss errors found in the literature cited. The analysis is based on the classical soil mechanics, including the Biot type approach
