| 摘 要： | 通常CSAMT采用的观测方式为发射设备摆设在距测线约6～8km的位置上，发射极与接收极平行放置．但在高山峡谷区，发射和接收装置因地形影响而不能按最佳方式布设．本文以1D正演EM波的技术为手段，研究了适合高山峡谷区的几种可能的CSAMT观测系统．比较了他们的优缺点．文章还对相应的反演方法提出了建议．

| Abstract: | Generally the observation mode is used in field CSAMT observation. The vertical distance from observation line to source part is about 6-8km, the current poles A and B line is parallel to the receiver pole's line. In the high mountain and steep gorge area, because of sharp relief of earth topography, the source and receiver units can not be arranged as the above mentioned best mode. In this paper by means of 1D forward EM modeling technique, the CSAMT observation systems, which are suitable to the mountain and steepy gorge area, are studied. The advance and shore comings of these observation systems are compared. The suggestion of corresponding inversion method are proposed. |
