摘　　要：为探究石油类污染物迁移规律,模拟分析渗漏区地下水水位波动对石油类污染物迁移影响。利用GMS软件开展地下水流数值模拟,构建石油类污染物迁移模型。联立求解地下水流方程与石油类污染物迁移方程,获取石油类污染物迁移分布特征。结果表明:随着水位的不断下降,迁移距离先小幅度增长后大幅增长,从垂直方向看污染浓度逐渐呈现下降的情况,从水平方向看污染浓度先下降后保持在一定的浓度水平上;随着水位的不断上升,迁移距离先大幅度增长后平稳增长,从水平方向上看污染浓度呈现逐渐下降的情况,而从垂直方向上看污染物浓度先下降后上升。This studyexplores the migration law of petroleum pollutants,simulates and analyzes the impact of groundwater level fluctuations in the leakage area on the migration of petroleum pollutants.It utilizes GMS software to conduct numerical simulation of groundwater flow and constructs a migration model for petroleum pollutants.The study simultaneously solves the groundwater flow equation and the migration equation of petroleum pollutants to obtain the distribution characteristics of petroleum pollutant migration.The results indicate that as the water level continues to decrease,the migration distance first increases slightly and then increases significantly.From a vertical perspective,the pollution concentration gradually decreases,while from a horizontal perspective,the pollution concentration first decreases and then remains at a certain concentration level.As the water level continues to rise,the migration distance first increases significantly and then steadily increases.From a horizontal perspective,the pollution concentration shows a gradual decrease,while from a vertical perspective,the pollutant concentration first decreases and then increases.
