摘　　要：穿越地下水源地的输油管道在运行过程中可能对区域造成环境污染,尤其是发生泄漏事故时会对地下水产生严重影响。以穿越某水源地的输油管道为例,采用地下水模拟系统(GMS软件),对管道泄漏后,石油类物质在地下水的污染状况进行模拟,分别预测了污染物抵达含水层后的1年、5年、10年、15年和20年的持续污染情形,以及在地下水中的浓度分布。模拟结果显示,石油在地下水中沿着地下水流方向移动,在运移20年后,受污面积可达45 937.1 m2。根据模拟结果,提出了预防措施和防治方案,分别为设置防渗层、确定监测井位置、增设监测井以及迁移敏感区的井口位置,以期为实际工程提供参考技术支持。The oilpipeline that crosses the groundwater source may cause environmental pollution in the construction and operation process,especially when leakage accidents happen. The oil into the groundwater will lead to the damage of water quality and ecological environment. Take the pipelines in one water source place as the case,this paper makes a simulation of groundwater pollution after a pipeline leakage accident,in which the groundwater modeling system（ GMS） is applied to simulate the concentration distribution of contamination after 1,5,10,15,20 years. The results indicate that the oil flows following the groundwater and after 20 years,the polluted area will be up to 45 937. 1 m^2. According to the simulation,several prevention measures are proposed,such as setting impervious layer,determining the location of the monitoring well,adding monitoring wells and migrating wells in the sensitive area,so as to provide references for practical engineering.
