摘　　要：近年输油管道泄漏事故频发,为更好地处置输油管道泄漏事故对河流污染造成的环境影响,预测输油管道泄漏后油品在河流的溢油进程十分关键。基于河流水体环境特点及河流环境溢流特点,比选出合适的基本控制方程及水动力数学模型,同时选择符合河流特征的溢油扩散、漂移及风化模型,模拟溢油运动与归宿;改进了Fay模型、简化了Navy漂移模型,建立了新的河流溢油环境影响评价模型,开发了河流环境影响评价计算软件,并应用于实际河流水体现场,证实了该模型和软件的适用性。In recent years, leakage accidents of oil pipeline have occurred frequently. To better dispose the environmental effects of such leakage, such as river pollution, the predication of overflow process after oil pipeline leakage is critical. Considering the environmental characteristics of river waters and the overflow in river, appropriate basic control equation and hydrodynamic mathematical model are recommended, Meanwhile, overflow diffusion, drift and weathering models conforming to the river characteristics are selected to simulate the overflow movement and homing. The Fay model is improved, Navy drift model is simplified, and a new environmental effect assessment model for oil overflow into rivers is developed. Moreover, the river pollution assessment software is developed. The model and software are applied to the river sites, successfully verifying their applicability.
