摘要

摘要本文介绍了在二维浅水模型框架内对孤波与稳定矩形半潜结构相互作用的数值模拟。研究结果与基于非旋转三维流模型的计算结果进行了比较，结果表明，在入射波幅较小的情况下，模拟精度令人满意。研究还发现，在使用一维浅水模型时，如果忽略了圆柱体表面的孤波衍射，那么圆柱体边缘的波浪上升最大值和其上的力载荷就会被高估。

NUMERICAL ANALYSIS OF INTERACTION BETWEEN A SOLITARY WAVE AND A RECTANGULAR FIXED SEMI-SUBMERGED STRUCTURE

This paper describes a numerical simulation within the framework of a two-dimensional shallow water model of interaction of a solitary wave with a steady rectangular semi-submerged structure. The results of this study are compared with the results of calculations based on a model of irrotational three-dimensional flows, and it is shown that the simulation accuracy at small incident wave amplitudes is satisfactory. It is also revealed that, the solitary wave diffraction on the cylinder surface is neglected when using a one-dimensional shallow water model, then the maximum values of wave runup on the edge of the cylinder and the force loads on it become overestimated.
