摘　　要：拟建的某填埋垃圾场位于四川盆地西部,垃圾场运行中产生的渗滤液必将对周围环境造成一定影响.本次模拟运用Visual ModFlow软件对渗滤液在地下水中的迁移扩散进行模拟研究,研究结果表明:正常情况下,污染物在一定范围内扩散和运移,影响距离及浓度都较小,不会迁移至附近地表水系。而对渗滤液事故情况下,污染影响范围广,浓度大,持续时间长。The proposed landfill locates in western Sichuan Basin, and the leachate emissions will certainly pose some impact on the surrounding environment after the landfill construction is completed. Therefore, the software Visual Modflow was used in this study to simulate the migration and diffusion of leachate in groundwater, and the results showed that in normal cases pollutants migrated and diffused within a certain range, with a small impact distance and concentration, and they would not migrate to nearby surface water. However, on condition of leachate accidents, the impact had a long duration with wide range and high concentration.
