Objective
The topic of research programme, proposed additionally to the existing HCMPROGRAMME, is as follows: wave induced interaction between erodable seabed (sandy sediments) and horizontal cylinder placed on or partly-buried in it. An experimental sand theoretical study is planned to be conducted in order to identify the major physical processes of the wave-induced interaction between an erodable seabed (sandy sediments) and a horizontal cylinder-like body placed on or partly-buried in it. Both the hydrodynamic loading on the exposed surface of the dylinder as well as the pore pressure distribution on the buried surface are going to be measured. The resulting forces acting on the cylinder will be analysed and the stability of bottom profile will be recorded in variety of tests with different water/wave conditions. The experimental results will be verified by theoretical predictions, and a finite-element numerical method will be then applied to perform the analysis of the true coupled performance of the horizontal cylinder and a composite continuum, in which the two phases (soil skeleton and pore fluid) interact, and the generation of pore pressure is completely dependent upon the relative stiff ness of the components of the system. It is proposed to combine the above two close-related geotechnical and hydrodynamic aspects of the governing problem. In order to get sufficient information and data needed for elaboration of a realistic mathematical description a series of laboratory experiments is proposed: qualitative small-scale model tests (Marine Civilk Engineering Department, Technical University of Gdansk), and as a main part of the proposed programme -extensive, quantitative measurements in a close cooperation with the Franzius-Institute (University of Hannover) where very unique and high-tech facilities like: the large wave flume (GWK) and LDA technique (Laser Doppler Anemometry) can be used.
This research project will become part of the original proposal in context with the HCM programme envisaging a European exchange of knowledge and skill in this hydrodynamic and geotechnical field of research.
