摘　　要：本文建立了考虑泥沙吸附和泥沙冲淤对污染物输移扩散影响的岸边排放污染物浓度场三维浑水水质模型,并模拟了三峡库区涪陵磷肥厂排污口附近的总磷浓度场。浑水水质模型的计算结果与传统清水水质模型的计算结果以及实际观测的结果之间都作了对比,结果发现在同一来流和排污条件下,两种模型计算得到的沿水深平均的污染物浓度场分布比较接近,而沿水深方向的污染物浓度分布有比较明显的差别。与实测结果的对比分析表明:浑水水质模型的计算结果比传统清水水质模型更接近实际。A 3-D water quality model of sediment-laden flow for side discharge is developed, in which the sediment adsorption and the sediment movement are taken into account. The concentration field of TP near Fuling phosphate fertilizer factory outfall in Three Gorges Reservoir is computed by both the model presented in this paper and the traditional water quality model. The results are compared with the field observation data. The comparison shows that there is little difference between these two models abount the averaged depth concentration fields, and the agreement between the computations and the field observation appears acceptable. Further more, the TP concentration along the vertical direction computed by the model presented in this paper varies distinctly from the result of the traditional quality model, and is closer to the field observation.
