【摘要】 在山区获得的 MT野外资料不可避免地受到各种干扰及地形与局部异常体的影响 ,常规方法很难满足山区 MT资料处理与解释的要求。本文提出了山区 MT资料精细处理方法 ,与常规资料处理方法相比较 ,主要从以下三个方面进行了改进 :1TE与 TM极化曲线的精细识别 ;2二维精细反演 ;3电法、地质交互式处理解释。实测资料处理表明 :采用精细处理的方法来进行解释 ,与常规方法相比 ,得到了较好的地电剖面。更多还原

【Abstract】 Field MT data obtained in mountain region are inevitably effected by different interferences, topography and local anomalous body, conventional techniques hardly meet the requirements for MT data processing and interpretation in mountain region. The paper demonstrated the fine MT data processing technique in mountain region which has improvements mainly in three aspects as compared with conventional processing: (1) fine identification of the TE and TM polarization diagrams; (2) fine 2 D inversion; (3) interactive processing and interpretation between electrical prospecting and geology. Real data processing shows that interpretation using fine processing can result in a good geoelectric profile as compared with conventional technique.更多还原
