摘　　要：采用三角型网格系统结合有限体积法,建立河北省曹妃甸海域的潮流数值模型,潮位、潮流数值模拟结果与实测值符合良好,在近岸水动力场模拟结果基础上,耦合基于油粒子模式的海上溢油漂移扩散数值模型,对曹妃甸南部甸头航道交汇区域的船舶相撞溢油事故进行了数值模拟研究。研究中拟合了该区域风场与潮流涨落的不利效应的叠加,对该海域船舶相撞溢油事故各响应时间节点处油膜运动可能产生的最大漂移距离、扫海面积及运动趋势等进行了分析。Based on the unstructured system,the finite volume method of tide and tidal current in the sea area of Caofeidian was established.The tidal current numerical simulation results agreed well with the measured values,and the hydrodynamic data was provided for the oil spill model to predict the influence of oil leak accident caused by ship collision at the interchange area of ship channels.In this paper,the adverse effects superposition of wind field and current field was coupled,the maximum drift distance,sweeping area and transport trend of oil slick were analyzed in detail.
