摘　　要：边坡问题是露天矿山当前面临的一个重要安全问题,但地质雷达数据中大量隐藏信息未被充分利用与挖掘是制约地质雷达应用于边坡滑体精细探测效果的重要因素。针对该问题,笔者根据研究区露天边坡滑体特点将多属性分析技术引入地质雷达解释分析中,优选并提取了振幅属性、瞬时属性、频率属性等多种属性对边坡岩土体结构和地下水进行了精细分析,最后分别与高密度电法反演剖面及水文孔进行了验证对比。实践证明,地质雷达信号多属性处理与解释成果反映的信息准确丰富,在露天矿边坡滑体探测中切实有效,可为后续露天矿边坡滑体治理提供准确可靠的依据。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 detection 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 respectively.It has been proved that the multi-attribute processing and interpretation of GPR signals reflect accurate and rich information.It is practical and effective in open pit slope slide detection and can provide an accurate and reliable basis for subsequent open pit slope slide management.
