EH-4大地电磁法探测地下暗河

Exploration of underground river using EH-4

通过一个实际工程勘查实例,介绍EH-4大地电磁法探测地下暗河的应用效果。给出电阻率二维反演断面与地质勘探剖面的对应情况,并指出EH-4大地电磁法反演工作中存在的主要问题。

With an actual engineering exploration as an example,this paper introduced the result of application of EH-4 in exploration of underground river,gave resistivity 2-D reversion section against geological exploration section,and pointed out major issues with EH-4 reversion.
