灰色关联法的输油管道泄漏河流污染影响评价方法研究

River Pollution Impacts of Oil Pipeline Leakage Based on Grey Correlation Method

为提高输油管道泄露河流污染影响评估的准确性,提出灰色关联法的输油管道泄露河流污染影响评价方法。该方法采用GMS中的MODFLOW模拟河流中溢油扩散情况,引入灰色关联法,结合溢油扩散情况,通过贴近度优化该算法后评价河流污染影响,获得河流水质等级,实现输油管道泄漏河流污染影响评价。应用结果表明,断面2和断面5的水质污染等级分别为III和IV,剩余断面的水质污染等级为II,该评价结果与实际结果一致,表明该方法可准确完成输油管道泄露河流污染的影响评价,具备了一定的评价准确性。

In order to improve the accuracy of oil pipeline leakage river pollution assessment,a grey correlation method was proposed.In this method,MODFLOW in GMS is used to simulate oil spill diffusion in a river,grey correlation method is introduced,and combined with the oil spill diffusion situation.The impact of river pollution is evaluated by optimizing the algorithm through proximity degree,and the river water quality grade is obtained to realize the impact assessment of river pollution caused by oil pipeline leakage.The application results show that the water pollution levels of sections 2 and 5 are III and IV,respectively,and the water pollution levels of the remaining sections are II.The evaluation results are consistent with the actual results,indicating that the method can accurately complete the impact assessment of river pollution from oil pipeline leakage and has certain evaluation accuracy.
