摘　　要：地质雷达技术是一种无损探测技术,可以利用电磁波在地下的反射和折射,探测地下的结构、岩层、土壤和地下水等信息。基于地质雷达探测方法,通过布置合理的探测测线,查明探测区域内与渗漏有关的土体不均匀沉降、不密实和脱空异常分布情况,最大探测深度不小于9m。地质雷达隐患探测的范围与圈定的范围基本一致,具有一定的精准性,可以在相似的工程中加以应用。Ground penetrating radar technology is a non-destructive detection technology that can utilize the reflection and refraction of electromagnetic waves underground to detect information such as underground structures,rock layers,soil,and groundwater.Based on the geological radar detection method,by arranging reasonable detection lines,the uneven settlement,non-compaction,and abnormal distribution of soil related to leakage in the detection area were identified,with a maximum detection depth of no less than 9m.The range of hidden danger detected byground penetrating radar is basically consistent with the delineated range,and has a certain degree of accuracy,which can be applied in similar projects.
