摘　　要：为了研究波浪作用下多孔海床瞬时孔压的渗流特性,采用模型试验与数值模拟相结合的手段。用粗砂制成孔隙率为0.5的模型海床,并在波流水槽中进行模型试验获取实测结果,然后运用波浪渗流力学和线性波理论使用有限差分软件FLAC进行数值模拟。将数值模拟结果绘制成图与实测结果进行比较,分析多孔海床在不同深度、水深和波况下的渗流特性。In order to study the wave-induced seepage characteristics of transient pore pressures within the porous seabed, this article will combine the model test with the numerical simulation method. This seabed model made by coarse sand of 0.5 porosity is used in the wave flume model tests to collect the measured results. FDM program FLAC is used to execute a numerical simulation on the basis of permeation fluid mechanics and linear wave theory. The results of numerical simulation will be drawn with measured value to contrast and analyze different depths and porous seabed depths and wave conditions of the seepage properties.
