摘　　要：本文设计了在防波堤上预留渔船通道的两种方案,并对其可行性进行了研究论证。研究采用Mike 21中的三角形网格水动力模块,利用二维浅水方程,进行潮流数学模型分析。研究结果显示从横向流速和工后流场方面分析,各方案均无法满足安全通航要求。通过研究得出如下结论:在高标准航道防波堤上预留渔船通道是不合理、不科学、不满足通航安全要求的,该结论可以推广应用至类似防波堤平面布置研究当中。A feasibility study has been made for two design plans of reserving fishing boat passage through the breakwater.A triangular grid hydrodynamic module based on Mike 21 is combined with two-dimensional shallow water equation to carry out the mathematical model analysis of tidal current.The results show that the above plans are unable to meet safe navigation requirement according to the transverse flow velocity and post-construction flow field.Thus it is unreasonable,unscientific,and unsafe to reserve a fishing boat passage through the breakwater that shields a high-standard channel.This conclusion is applicable in the layout study of similar breakwaters.
