| 摘 要： | 本文采用斜分层有限元模型模拟了三峡水库蓄水前后万州江段的流速场和浓度场.通过计算龙宝河排污口和苎溪河排污口附近水域污染混合区的范围,分析比较了蓄水前后排污口的位置、水位流速变化对污染混合区的影响.结果表明,在相同的排污负荷下,排污口所处位置的不同,所形成污染混合区的范围相差很大,尤其在水库蓄水运行后这种差别更为显著,因此必须合理地规划和布置库区排污口,保证库区水体功能要求.

| Abstract: | A Non horizontal Multi Layer Finite Element Model is applied in this paper to simulate the flow and the concentration of Wanzhou Reach in The Three Gorges Reservoir(TGR).The pollutant zones near the Longbaohe discharge outlet and Zhuxihe discharge outlet are calculated from the concentration distributions.The comparison between the pollutant zones of these two discharge outlets shows that the pollutant zone varies greatly with the location of discharge outlet.It is indicated that polluatnt zone will enlarge after Three Georges Project is completed.It is very important to arrange the discharge outlets reasonably and meet the demand for water quality. |
