TLDR
In this paper, the pore pressure as a function of the wave pressure was determined for a wide class of wave pressure forms, and an analytical relationship between stresses and pore pressures was established, which is sufficient to solve the complete effective stress problem.Abstract:
This note describes the determination (for a wide class of wave pressure forms) of the response to waveloading of an infinite half-space consisting of a porous elastic soil skeleton. Under such loading, no volumetric strains occur in the soil mass, and there is no coupling between the pore water and the skeleton. Also, an analytical relationship has been established between stresses and pore pressures, so that the computation of the pore pressures is sufficient to solve the complete effective stress problem. The paper gives an integral formulation for the pore pressure as a function of the wave pressure.read more

Soft-sediment deformation structures induced by cyclic stress of storm waves in tempestites (Miocene, Guadalquivir Basin, Spain)
TL;DR: In this paper, the authors analyse soft-sediment deformation structures in Upper Miocene calcarenitic tempestites of the Guadalquivir Basin (Southern Spain) and conclude that liquefaction was triggered by pore pressure changes induced by cyclic and residual stress of storm waves.

Diastasis cracks: mechanically generated synaeresis‐like cracks in Upper Cambrian shallow water oolite and ribbon carbonates
Clinton A. Cowan,Noel P. James +1 more
TL;DR: In this article, the authors proposed an alternative explanation that cracks occur in carbonate mudstone interbedded with ooid and peloid grainstone (unwashed oolite and ribbon rock lithofacies) in the Upper Cambrian limestones and dolostones of western Newfoundland, Canada.

Response of cross-anisotropic seabed to ocean waves
TL;DR: In this paper, quasi-static field equations for fully saturated porous elastic media, based on Biot's theory, established in the writer's previous works (1989−1990) are used to describe the behavior of such materials under wave ocean loading.

Pore Pressure, Stress Distributions, and Instantaneous Liquefaction of Two-Layer Soil under Waves
TL;DR: In this article, the instability of two-layer porous soils subjected to harmonic waves is investigated in terms of instantaneous liquefaction, and the governing equations are written in their fully dynamic form, and possible simplifications are introduced.

Wave pressures and uplift forces on and scour around submarine pipeline in clayey soil
TL;DR: In this article, the authors investigated wave-induced pressures and uplift forces on a submarine pipeline (exposed, half buried and fully buried) in clayey soil of different consistency index both in regular and random waves.
