根据椭圆余弦波理论，计算了在滨浅海区域波浪作用下海床表面的波压力．通过参数分析，研究了海床弹性参数、渗透性以及孔隙水的压缩性对椭圆余弦波作用下海床孔压响应的影响．研究表明：孔隙水的压缩性、海床的渗透性、剪切模量、泊松比对海床的孔压响应有明显的影响，海床的渗透各向异性对孔压响应影响较小．

The water pressure on the surface of the seabed was obtained with the cnoidal wave theory usually employed in coastal regions to analyze the interaction between the structures and waves. Dynamic responses induced by the cnoidal water waves in seabed sediments were investigated with numerical methods. Parametric studies were conducted to indicate the influences of the elastic constants, seepage characteristics and the compressibility of the pore water in analytical and numerical calculations. The results show that the excess pore pressures are extensively affected by the compressibility of the pore water and the seepage coefficient, whereas the anisotropy of the soil permeability has little impact on the pore pressure. The shear modulus and the Poisson's ratio used in the calculation also have some effect on the response of the seabed.
