某船舶修造工程对附近水域影响数值分析

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。

Numerical analysis impact of ship building & repairing on surrounding waters

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 m...
