| Abstract: | This paper investigates the seepage pressure in porous elastic seabed underneath two vertical circular cylinders by a finite element method, which is matched with an outer field solution established. The influence of charge of the distance between cylinders on the seepage force of each cylinder is investigated for two-kind incident waves of sine and cnoidal waves and for various arrangements of cylinders. The governing equation for seepage pressure is based on the Biot' s consolidation theory. The wave pressure on seabed is calculated by the water wave potential theory. Experiments measuring seepage pressure at the bottom of cylinders are conducted. The agreement between numerical and experimental results of seepage pressure is satisfatory. |
