摘　　要：基于FLOW-3D软件,采用推板造波及孔隙消波相结合的方法构建三维数值波浪水池,研究直立堤在波向与迎浪面小角度(≤15°)变化时所受波浪力。数值模拟结果表明:1)墙面测点波浪力在各堤面坡度及各测点之间随波向的变化趋势大体相似,在90°波向时有最大值。2)同一堤面坡度下墙底各测点之间波浪力随波向的变化趋势不尽相同,同时堤面坡度的存在会影响其变化趋势。3)波浪力在墙面上的分布,无论是在何种堤面坡度或任一波向作用下都基本相同。4)墙底波浪力近似梯形分布。5)在大多数波向下,墙面及墙底测点波浪力的最大值出现于堤面具有一定坡度时。By the software FLOW-3D,a three-dimensional(3D)numerical wave pool is constructed by the combination of the piston-type wave generation and the pore wave absorption to study the wave force on the vertical breakwater when the wave direction and the sloping wall change at a small angle(less than or equal to 15°).The following conclusions can be drawn by the numerical simulation:1)For the wave force at the measuring points on the wall,it has a similar trend to the wave direction at all slopes of the breakwater and among all measuring points,and it reaches the maximum at a wave direction of 90°.2)At the same slope of the breakwater,the variation trend of wave force with the wave direction among all measuring points at the bottom of the wall is not the same,and the slope of the breakwater can affect the variation trend.3)The distribution of wave force on the wall is basically the same regardless of the slope of the breakwater or the action of any wave direction.4)The distribution of wave force at the bottom of the wall is approximately trapezoidal.5)In most wave directions,the maximum wave force at the measuring points on the wall and at the bottom of the wall occurs when the breakwater has a certain slope.
