摘　　要：为探究高密度电法与地质雷达在路基边坡探测中的应用,文中通过理论分析和现场试验研究二者的探测原理及现场探测效果。结果表明:水、空洞及不同密实度的岩土体的电阻率不同,通过分析高密度电法探测的电阻率分布云图,可直观判定低阻异常区域。地质雷达根据电磁波反射信号的强弱和波形信息探测路面下方地质条件。高密度电法与地质雷达探测结果表明试验路基边坡下方存在富水或空洞异常区,二者探测结果一致,后经证实取土检测结果无误,联合探测取得良好效果。In order to explore the application effect of high-density electrical method and geological radar in subgrade slope detection,the detection principle and field detection effect of the two methods were studied through theoretical analysis and field experiment.The results show that the resistivity of water,cavity and soil with different compactness is different,and the low-resistance anomaly area can be intuitively determined by analyzing the resistivity distribution map detected by the high-density electrical method.Geological radar detects the geological conditions under the road surface based on the strength of the electromagnetic wave reflection signal and waveform information.The detection results of high-density electric method and geological radar showed that there was a water-rich or cavitary anomaly area under the slope of the test subgrade,and the detection results were consistent.
