摘　　要：对一个有近40年历史的废弃加油站,分别使用探地雷达方法和高密度电阻率法进行探测,同时布置了4口监测井进行取样分析,以验证两种方法探测石油烃类轻质非水相液体(LNAPLs)污染物的准确性。测量结果明确显示了污染源及其扩散范围。实际应用证实了探地雷达与高密度电阻率法可以作为有效的工具在加油站及类似场地用于环境探测。The studied site is located within an abandoned gas station which had nearly existed for 40 years. The authors used ground penetrating radar and high density resistivity method to detect the petroleum hydrocarbon contamination. At the same time,four monitoring wells were drilled in the gas station and samples of groundwater were analyzed so as to verify the accuracy of the two methods in detecting light non-aqueous phase liquids( LNAPLs) contamination. Comprehensive detection results showed that the source of pollution was the leaking pipes,the diffusion range reached the gas station boundary and the vertical distribution of con-tamination was about 0. 5 ~ 2. 8 m. Ground penetrating radar and high density resistivity method used in the investigation provided an excellent tool for environmental detection,suggesting that they can be applied to the study of similar areas.
