【摘要】 为使三峡水质预警系统有效模拟预测三峡溢油事故,建立了适应该系统的平面二维河道溢油模型。常见溢油模拟的做法是在溢油自身扩展阶段采用Fay模型、在溢油飘移阶段采取油粒子模型,而文章使用根据Fay模型进行扩展之后的油粒子模型,该模型可在溢油的自身扩展和漂移阶段同时使用。该模型结合了油粒子模型和Fay模型的长处,既解决Fay模型只能用于静止海面上的限制,又解决了油粒子模型不能模拟溢油自身扩展阶段的难题,特别适用于水域相对海洋狭小且形状复杂,水流也较复杂的河流溢油模拟。将其运用为三峡水质预警系统的溢油模拟模块,取得了较好的效果。更多还原

【Abstract】 A plane two-dimensional river oil spill model was developed,which is effective in modeling river oil spill accident in advanced warning system of Three Gorges water quality.For common oil spill modeling,FAY model is used in oil spill spreading period and oil particle model is used in oil-spill transport period.An oil particle model based on FAY model can be used in both spreading period and transport period,which destroy the limits of FAY model that is only used for static marine,and solve the problem of oil particle model that can not model oil spill spreading.The integrated model is especially suitable in modeling river oil spill accident happening in narrow and complicated water area where flow is complicated too.The model is used for advanced warning system of Three Gorges water quality,with satisfactory results.更多还原
