中文摘要：

波浪向近岸传播的过程中由波浪破碎等效应所形成的近岸波流场是近岸缓坡区域重要的环境动力因素之一。本文基于近岸波浪传播的缓坡模型对近岸波浪场及近岸波浪斜向入射破碎后所产生的沿岸波流场进行了数值模拟。考虑到波浪向近岸传播中局部复杂区域波向不易确定，计算时直接从波浪辐射应力定义出发。采用抛物型缓坡方程所给出的辐射应力公式来计算波浪产生的辐射应力，在此基础上耦合近岸波流场数学模型对近岸波浪破碎形成的波流场进行了数值模拟研究，结果表明本文的数值模型是有效的。

英文摘要：

The near-shore wave-current field formed by the breaking of oblique incident wave .is numerically simulated by applying the mild slope equation for describing the wave propagation in coastal zone. In consideration of the difficulty of determining the direction of wave in local complicated region in the process of wave propagation, the formula deduced from mild slope equation for calculating the radiation stress generated by the wave action is adopted. On this basis the model for describing the wave current field is coupled with the broken wave current field model to realize the numerically simulate of the wave current field in coastal zone.
