Design levels for offshore structures. State-of-the-art and instantaneous pore-pressure model

Abstract

The report contributes to the development of an integrated design approach of monolithic (vertical) coastal structures commonly used in shore protection and harbour construction. A review is given on approaches using dynamic and probabilistic analysis, based on physical understanding of the hydraulic, geotechnical and structural processes involved in the wave-structure interaction for stability evaluation of coastal structures. Foundation analysis may be approached in two stages: feasibility (or so-called desk-top) study and more sophisticated studies using elastic theory, finite element analysis and boundary element method. The presented 1D finite element solution for the wave-induced pore pressure and soil matrix displacements is a convenient tool in solving the problem of instantaneous pore pressure.
