斜向波对岛式直立堤作用力的数值模拟

Numerical Simulation of the Forces Acted on Vertical Island Breakwater by Oblique Wave

国内多采用合田公式计算斜向波对直立式防波堤的作用，但公式中未考虑单个沉箱的防波堤轴线方向上的长度Ｂ这个因子。通过数值模拟可见，无量钢参数Ｂａｉｎα／Ｌ（α－波浪入射角，Ｌ－波长）是影响作用力的重要因素。

Hetian Formula is more often adopted in China for calculating the forces acted on vertical breakwater by oblique wave, in which the length (B) of a single caisson along the axial direction of breakwater is not considered. Numerical simulation shows that the measureless steel parameter Bsinα/L(α─wave incident angle, L─wave length) is an important factor affecting the forces.
