摘要	Numerous offshore structures have been constructed in severe ocean environments where waves are usually coexisting with current. Previous studies on the seabed response mainly focused on either wave induced pore-pressure in the soil or the particle-transport of surficial sediments, etc. In this study, the sandy seabed responses in combined waves and current were physically modelled with a specially-designed water flume. The flow velocities in the boundary layer and the pore-water pressure in the sand-bed were simultaneously measured with an Acoustic Doppler Current Profiler (ADCP) and miniature Pore Pressure Transducers (PPTs) respectively. In the physical modelling of wave-current coexistence, both the following-current and opposing-current were superimposed on the travelling waves respectively. Experimental results indicate that the pore-pressure amplitudes are enlarged for the following-current case and reduced for the opposing-current case. This coupling effect is more obvious for the waves with shorter periods. The wave-induced seepage has slight effect on velocity profiles in the boundary layer for the examined hydrodynamic loads and the medium sands. © 2010 Taylor & Francis Group, London.
