摘　　要：随着液体化学品船舶运输业的迅速发展,液化产品泄漏已对水环境安全造成重大威胁。液体化学品一旦发生泄漏,可能对水环境造成污染。本文在长江扬中段建立非恒定水动力数学模型,在此基础上,采用非稳态三维水质模型模拟可溶性液体化学品泄漏对下游取水口断面的影响,探索模拟可溶性液体化学品污染带的迁移过程,分析了污染物到达取水口的时间,取水口污染物浓度超标时间范围,为码头选址提供依据。With the rapid development of liquid chemicals shipping industry,the leakage of liquefied products has posed a great threat to the safety of the water environment. The water environment may be polluted once the leakage of chemicals happened. In this paper,a hydraulic model of unsteady flow in the Yangzhong part of the Yangtze river is established,and on this basis,the unsteady three-dimensional water quality model is adopted to simulate impacts of the soluble liquid chemicals leakage on the downstream intake section. The migration process of soluble liquid chemicals pollution has also been explored and simulated. The time when contaminants reach the water intake and the time range for above-standard pollutants concentration have been analyzed to provide the basis for the wharf site selection.
