| 摘 要： | 对三峡大坝一期围堰及二期围堰施工期不同的水流、污染物输运特性进行了分析,建立了三峡大坝坝下水域三维水量、水质模型。模拟结果表明,除在排污口形成的混合区内存在轻微污染外,由于大坝下泄流量较大,稀释能力较强,整体水质状况主要取决于上游来水水质,变化不大。

| Abstract: | Because of construction of the world famous.Three-Gorge Project,the local turbulent flow,compared to the original,has been changed greatly.The variation of hydrodynamics results in change of water environment.Based on the features of hydrodynamics and contaminant transportation of the water body affected by constructing the Three-Gorge Project's first- and second stage-cofferdam,this paper establishes a 3-D hydraulic and water quality model.The results of simulation indicate that there is a pollution zone in the area close to the discharge outlet,but the polluted range and the contaminant concentration is not big.Most of the water body is not affected and the water quality is close to that of inflow. |
