EH-4数据在IMAGEM与WINGLINK下反演处理的对比

THE CONTRAST AND ANALYSIS OF EH-4 DATA PROCESSED WITH IMAGEM AND WINGLINK SOFTWARE

对目前在工程上应用比较广泛的2款大地电磁勘察反演软件——基于博斯蒂克(BOSTIK)方法的IMAGEM软件和基于非线性共轭梯度(NLCG)方法的WINGLINK软件的特点进行了对比研究。这两款软件在反演方法、操作系统平台、数据编辑、静态校正、反演效果等方面有很大的不同。在此基础上,对兰渝线某隧道工程EH-4大地电磁资料的反演解释实例进行了分析,认为两款软件各有侧重,建议结合使用。

Among all MT Inversion methods used at present,there are two sorts of MT Inversion software which have mature system and have been widely used in engineering: One is the IMAGEM software applying inversion method of ' Bostik',and the other is the WINGLINK software applying inversion method of ' NLCG'. There exist obvious differences between the two sorts of software in such aspects as inversion theory,operation system,smoothing pattern static correction and inversion result. On such a basis,the authors analyzed the inversion interpretation of EH-4 magnetotelluric data obtained in a tunnel of Lanyu Railway. The contrast and analysis of the data processed with the two sorts of software are demonstrated in this paper.
