摘　　要：利用平面二维浅水潮波运动方程和连续方程,结合1个实测潮位站和4个实测潮流点资料进行验证,得出较为符合实际的流场对工程附近的流场、冲淤影响及COD引起的水质进行分析。结果表明:围填西南侧产生一流速增大区,围填及码头附近产生一流速减小区;冲淤平衡后最大淤积量为1.2 m,冲刷量在0.1～0.3 m;COD在正常和事故排放情况下,对附近敏感点不造成影响。Using two-dimensional shallow-water tidal wave motion equation and continuity equation,combining with measured data of one tide station and four flow sites to verify the trend of points,obtained the realistic flow field,on which basis,the analysis that contain flow field,deposition and the water quality caused by the project could be obtained.The results show that： the southwest region produces the velocity increase,while the other regions of it and the area near the pier produce the velocity decrease.The maximum reducing of depth happens in deposition equilibrium up to 1.2 m;the increases of erosion change with the amount of decreasing distance from the dike erosion and scour,while the equilibrium volume of it is 0.1 ~ 0.3m.COD discharging in normal circumstances has little impact on the surrounding water;and when it happens in the accident,its influential sphere expands,but the impact on the surrounding water quality is still very small.
