摘要

随着电法勘探在工程勘察领域的不断扩展,对技术方面提出了一系列高难要求.高密度电法以成本低、效率高、信息丰富、解释方便、勘探能力强等特点被广泛应用,但也存在着用视电阻率解释成果异常不明显的问题.在提出用视电阻率比值参数解释成果基础上,从理论上研究了视电阻率比值参数的确反映异常的能力比较强.对废旧矿区采空区的勘探结果表明,视比值参数λ和视比值参数T反映异常的能力都明显比视电阻率参数高.
        As the expanding of electrical prospecting in the field of engineering investigation, a series of technical questions have been proposed. High density resistivity method is widely used, for it's low cost, high efficiency and abundant information, convenient explanation, high exploration ability, But there is also a problem that the apparent resistivity interpretation result is not obvious. On the basis of the results' interpretation with apparent resistivity ratio parameters, it is theoretically studied that the apparent resistivity ratio parameter is good at abnormal reflections.The exploration results in abandoned goafs show the ability that the apparent ratio parameters λand T reflect the anomaly is obviously higher than that of the apparent resistivity parameter.
