直流激电测深多参数综合分析划分含水异常岩体

直流激电测深观测 (计算) 的参数多, 现已成为一种有效的找水方法。但由于不同的地区存在各种不同的干扰, 因此, 合理、准确地综合利用这些参数, 减少多解性, 避免解释错误显得尤为重要。本文在分析原始实测参数的基础上, 对部分参数进行了转化, 使其抗干扰能力更强, 资料解释更可靠, 并通过实例评价了部分参数的优越性和局限性。应用实例表明, 多参数综合解释方法具有推广意义。

Division of water-containing abnormity using multi-parameter method of directcurrent induced polarization sounding

Recently the direct current induced polarization sounding method is widely used to detect the ground water, due to its multi-parameters. Because of the different disturb degree in different work area, it is important to use muli-parameters reasonably and accurately, reducing more explanations and avoiding mistake explanation. Based on analyzing primitive practical data, the paper transformed partial parameters to ensure to use them accurately and to get the more reliable data. A case study shows advantages and limitations of partial parameters. The result indicates that the synthetic interpretation method of multi-parameters is worth to be widespread.
