泥石流是地质灾害的主要类型之一,如何准确地探测泥石流层的厚度,对于判断泥石流的规模与地质灾害评价非常重要。本文简要叙述了探地雷达和直流电阻率测深法的探测原理,由于泥石流与基岩的物性有差别,因此应用以上两种物探方法探测泥石流理论上是可行的。通过探地雷达和直流电阻率测深法在泸定县泥石流区域的应用实例分析,证明了采用综合物探方法能够快速、有效地解决地质灾害方面的相关问题。
Debris flow is one of the major types of geological disasters. How to accurately detect the thickness of debris flow is very important for judging the scale of debris flow and geological disasters. This paper briefly describes the detection principle of GPR and DC resistivity sounding method. Because of the differences between debris flow and bedrock physical properties, it is theoretically possible to apply the above two geophysical methods to detect debris flow. Through the application of GPR and DC resistivity sounding in the debris flow area in Luding County, it is proved that the comprehensive geophysical prospecting method can solve the related problems in geological disasters quickly and effectively.
