경사식방파제에 작용하는 파력 결정에 관한 수치해석

Abstract

The evaluation of geodynamic stability of rubble mound breakwater such as sliding and settling require s the information of wave force acting on the breakwater. In the present study, a numerical method which can be practically used in determining wave force was presented. and was verified by hydraulic experiments. The strongly nonlinear wave deformation and resulting wave pressures on the frontal slope of the breakwater were calculated by a volume-of-fluid method. The peak values and phases of of pressure signal were shown to be linearly dependent on the surf similarity parameter. The results agreed quite well with experimental data, and their experimental formulas to a boundary element method for calculating the inner wave field of breakeater. It was shown that the calculated wave forces also agreed well with experimental data.
