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。
The MT field data acquired in the mountain area are inevitably affected by all kinds of interferences as well as topography and local anomalies. Conventional methods can hardly meet the requirements of MT data processing and interpretation in the mountain areas. In this paper, the method of meticulous MT data processing in mountain area is proposed. Compared with the conventional data processing method, this method is mainly improved from the following three aspects: fine identification of 1TE and TM polarization curves; 2-dimensional fine inversion; Interactive processing explained. Measured data processing shows that: using fine processing method to explain, compared with the conventional method, get a better geoelectric profile.
