| 摘 要： | 利用MIKE 21 HD模块模拟广西近海二维潮流特性,根据实测水文资料对广西近海二维水动力模型进行了验证。应用MIKE 21 OS溢油模块加载广西近海二维水动力数据,建立广西近海二维溢油扩散模型,对溢油事故进行影响预测。研究结果表明,风场、潮流场和溢油事故发生位置对溢油轨迹都有着重要影响。风场是油膜漂移方向的最大影响因素,在不同溢油事故发生位置的工况下,溢油的漂移轨迹和扫海范围可能完全不同。

| Abstract: | Two dimensional tidal characteristics of Guangxi offshore area were simulated by MIKE 21 HD module.According to the measured data,two dimensional hydrodynamic model of Guangxi offshore area was validated.Based on the two dimensional hydrodynamic data of Guangxi offshore area loaded by MIKE 21 OS module,the two dimensional oil spill model of Guangxi offshore area was built by MIKE 21 OS module,and the impact of oil spill accidents was predicted.Results show that the oil spill trajectory is mainly influenced by wind field,current field and location of accidental oil spill.Wind field is the most significant factor influencing the drift direction of oil film.Oil film trajectory and sea swept area can be totally different under different conditions of accidental oil spill location. |
