综合物探方法在河北保定地区地表基质层试点调查中的应用

Application of Comprehensive Geophysical Method to Ground Substrate Layer Pilot Survey in the Area of Hebei Baoding

摘要: 垂向结构特征调查是自然资源地表基质层调查的一项重要内容，也是工作中的难点问题。本文通过微动勘探、高密度电法、等值反磁通瞬变电磁法等综合物探方法在河北省保定地区地表基质层试点调查中的应用研究实例，并结合钻探、测井等数据进行验证，系统介绍了如何利用微动勘探、高密度电法、等值反磁通瞬变电磁法等综合物探手段研究地表基质分层特征，提出微动勘探在抗干扰强、分辨率好、对环境无破坏性方面有着综合全面的优势，反磁通瞬变电磁法无浅层勘探“盲区”，高密度电法效率高，后两者可以作为辅助手段。

Abstract: The survey of vertical structural characteristics is an important part of the survey of the ground substrate layer of natural resources, and it is also a difficult problem in the work. In this paper, the application of comprehensive geophysical prospecting methods such as micro tremor exploration, high-density electrical method, and opposing coils transient electromagnetic method in the pilot survey of the ground substrate layer in the Baoding area of Hebei Province is used for verification, and combined with drilling and logging data, systematically introduces how to use microtremor exploration, high-density electrical method, opposing coils transient electromagnetic method and other comprehensive geophysical methods to study the characteristics of ground substrate layer, and proposes that microtremor exploration has comprehensive advantages in terms of strong anti-interference, good resolution, and non-destructiveness to the environment. Opposing coils tran-sient electromagnetic method has no shallow exploration “blind areas”, and the high-density electrical method has high efficiency, and the latter two can be used as auxiliary means.
