Voxler及Surfer在乐滩水库引水灌区EH4资料处理中的应用

Application of Voxler and Surfer in EH4 data processing for Letan Reservoir Irrigation Zone Project

介绍了Voxler和Surfer两种视图软件在乐滩水库引水灌区加旦~良马隧洞2#段高频大地电磁法(EH4)规则测网探测试验中的应用情况,通过三维视图软件Voxler处理EH4资料得到卡尼亚视电阻率三维空间分布图,结合常规视图软件Surfer处理EH4资料得到的卡尼亚视电阻率二维组合断面图,能更直观地显示EH4的探测成果,能更有效提取原始资料中的三维信息,为EH4成果提供更多的解释依据。

For the No.2 seetion of Jiadan-Liangma tunnel of Letan Reservoir Irrigation Zone Project, survey had been conducted hy high frequency magnetotelluric method （EH4）. An introduction was made on tile application of Voxler and Surfer in survey of EH4 rule grid. The EH4 data was processed with two kinds of view software of Voxler and Surfer to render Cagniard resistivity 3D spatial distribution map and 2D composite sectional graph respectively, permitting more visual display of EH4 survey achievements and effective extraction of 31） information out of original data, so as to provide more explaining basis.
