摘　　要：结合新疆某电厂工程,基于研究区环境水文地质条件,建立数学模型,分析电厂生产过程中石油类渗漏可能对地下水污染的影响,对污染物在潜水含水层运移和变化进行了数值分析。结果显示,石油类污染物运移方向与地下水流方向基本一致,因弥散作用导致污染羽面积不断扩大。污染物浓度迁移曲线呈正态分布,在污染源下游400m处,污染物运移9年时浓度达最大值0.16mg/L。预测20年后石油类污染物渗漏对潜水含水层的影响范围扩大到36 400m2,最大运移距离为1 297m,其污染物运移已超过地下水平均水流所波及的范围。Numerical method was adopted in this paper to simulate the migration of petroleum contaminants in the phreatic aquifer using the data from an electric factory of Xinjiang.Simulating results show that the main direction of migration of petroleum contaminants is same as the shallow groundwater.Diffusion,however,may cause the leakage of contaminants.The dispersion of petroleum concentration follows a normal distribution pattern.At the place 400 meters far from the pollution source,the concentration of contaminants may reach 0.16 mg/L within 9 years.The pollution speed gradually increased in the beginning and decreased at last,but the leakage of petroleum was increasing gradually.It is estimated that the influence of petroleum contaminants may expanded up to an area of 36 400 m2 in about 20 years.The maximum migration distance may reach 1 297 m,which exceeds the groundwater migration distance.
