摘要
In this paper, the irregular wave-induced seepage action on cylinders resting on rubble mound foundatoin (RMF) is studied by means of finite element method (FEM). The hydraulic resistance inside RMF is assumed to satisfy the nonlinear Forchheimer's equation and the seepage in the scabed is also considered. Model tests show good agreementwith the numerical results. The influence of several main parameters is discussed on the basis of vast calculations. In addition, the ratio of seepage forces, induced by regular and irregular waves respectively, is analyzed and thus a computaional method is put forward for practical engineering application to simplify the calculation of irregular wave-induced seepage forces.
