摘要
本文结合大窑湾港区建设的实际工程，计算了大窑湾潮流场及悬浮物浓度的沉降扩散。采用垂向平均的二维潮流场模型，其开边界条件考虑了海湾内潮波反射的影响，潮流场的计算结果与实测值比较符合。对具有沉降项的悬浮物浓度对流扩散方程也采用垂向平均处理，给出了其合理的表达，结合潮流场的实测及计算数据，确定了沉降项中的参数。计算的浓度分布结果为工程环境评价提供了有益的依据。
To applicate to the building engineering of Dayaowan harbour. we calculated the tidal current and suspended sediment transport in Dayao Bay with 2-D depth integrated model and the boundary condition taking account of the effects of reflect wave in the bay. The calculational results of tidal current agree well with the observation data. The calculational results of suspended concentration provide significant referential data for environmental evaluation.
