THE RESPONSE OF FINITE THICKNESS SAND-BED TO WAVE LOADING

In this paper, the continuum mechanics of water-soil mixture is adoptof for analysing the response of finite thickness sand-bed to wave loading. The sand-bed is treated as a saturated porous elastic medium and Biot's theory is used to formulate the coupled flow and deformation. The waves are described by linear water waves. Under the above assumptions, the basic equations are obtained for describing the response of soil-bed to wave loading. The distribution of displacements, stresses and porewater pressures...
