The slope problem is an important safety issue in open pit mines,but the large amount of hidden information in GPR data is not fully utilized and exploited,which is an important factor limiting the effect of GPR application in the fine detec-tion of slope slides.To address this problem,this paper introduces multi-attribute analysis technology into GPR interpretation and analysis according to the characteristics of open-air slope slides in the study area,preferably extracting various attributes such as amplitude attribute,instantaneous attribute,and frequency attribute for refined analysis of slope geotechnical structure and groundwater,and finally verifying and comparing with high-density electrical inversion profiles and hydrological holes re-spectively.It has been proved that the multi-attribute processing and interpretation of GPR signals reflect accurate and rich in-formation.It is practical and effective in open pit slope slide detection and can provide an accurate and reliable basis for subse-quent open pit slope slide management.
