%X 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 in the deposit are given by analytical-numerical method and then the theoretical results are compared with the experimental data of a wave-sandbed model test. The parametric properties affecting the response of soil-bed to wave loading are also analysed and discussed. According to the parametric studies and the results of comparison between the theoretical calculation and experimental data, it is concluded that the theoretical model and calculation method presented in this paper can be used to evaluate the response of seafloor to storm wave loading.
