摘要
随着三峡库区通航条件的改善和船舶流量的不断增加,库区水上溢油风险形势日益严峻.文中以一维圣维南方程和二维EFDC模型为基础,实现了一维、二维水动力的耦合模拟,而后结合"油粒子"漂移扩散模型设计了一个适用于三峡库区水上溢油预测模型.在此基础上对175m水位的万州段长江干流的假想溢油事故进行了进行模拟,初步检验了溢油预测模型的效果.
With the improvement of navigation environment on the Three Gorges reservoir area,the risk of oil spill becomes more and more serious.The paper selects one-dimension Saint-venant equation,two-dimension model-EFDC and coupled them.After that,＇spillet＇ drift model has been put together with the hydrodynamic coupled model to form a oil spill forecast model system.Finally,the system has been used to simulate a oil spill case that occurs on the Wanzhou of Changjiang River and the result has been analysed.
