摘要
在泥石流调查中,查清泥石流区域覆盖层厚度及基岩分界面对泥石流地质灾害的评价非常重要。该文将浅层瞬变电磁法用于北京市某地泥石流勘察中,特别是在场地受限、接地条件极差的区域,该方法显示了优越性。经过钻探和探坑的验证,浅层瞬变电磁法探测取得了令人满意的效果,是泥石流勘察的一种新方法。
In the debris flow investigation,detecting the thickness of the boundary area in the debris flow area and bedrock interface is very important to evaluate the geological hazards of debris flow. In this paper,the transient electromagnetic method with shallow subsurface is used to a debris flow investigation in Beijing. Especially in the area with limited site and poor grounding condition,the method shows the superiority. Through the verification of drilling and pit,the transient electromagnetic method with shallow subsurface achieves satisfactory results,and it is a new method for debris flow investigation.
