| 摘 要： | 利用Cole-Cole模型组合和稀释系数理论，可以描述测量得到的视复电阻率频谱与地下多个电性体SIP真参数之间的正演关系。本利用此正演关系进行反演试算，并比较了几种Cole-Cole模型反演方案的效果；提出固定极化目标体和围岩体的极化率同时反演其它各SIP真参数的反演方案。结果表明在固定极化率为真值时，利用此反演方案可以稳定、准确、快速地得出地下电性体SIP真参数。

| Abstract: | The relations between SIP real parameters of underground anomalous body and apparent complex resistivity spectra can be expressed by the combination of Cole-Cole models and dilute coefficient. In this paper, we use the modeling expression to compare several SIP inversion schemes with Cole-Cole model, and bring forward a new inversion scheme, it is fixing the polarizability of polarizable object body and adjacent rock, then simultaneity inverse other SIP parameters. Through a great deal theoretic checking computations, we find when polarizability is fixed, this inversion scheme has good stability, veracity and velocity. |
