摘　　要：通过地球物理探测方法测试土层电阻率,利用电阻率的异常判别筛查场地污染分布范围,是国内环境岩土工程领域关注的热点问题。本文基于现场试验与工程应用,探讨高密度电法、电阻率CT、电阻率静力触探(RCPT)对污染土诊断的适用性。结果表明,电阻率测试可快速诊断场地潜在污染区域,操作简单、结果可靠、成本较低,在污染场地初步调查中有较高的应用价值与优势。In the domestic environmental geotechnical engineering field, abnormal soil electrical resistivity values are used to discriminate and screen contaminated soils using geophysical exploration methods. Based on in situ experiments and engineering applications, this study discusses the applicability of the high density electrical method, the resistivity computerized tomography method, and the resistivity cone penetration test (RCPT) for contaminated soil diagnosis. The results show that electrical resistivity testing can be applied to rapidly diagnose the potential contaminated area. It is simple to operate, provides reliable results at a low cost, and has high application value and advantages in the preliminary investigation of contaminated sites.
