摘 要: 针对广东省某水利枢纽防护堤的管涌事故,采用加拿大EKKO专业地质雷达,对防护堤土层的密实程度和管涌等病害情况进行了无损探测。根据反射波在含水土层与干燥土层的介电性差异,对地质雷达数据进行解译,判断管涌渗漏通道的位置,为制定加固方案提供了科学依据。 People took a scatheless detection for soil compaction and piping disease of a water conservancy dike piping accident in Guangdong Province by EKKO PRO GPR. GPR data was interpreted according to difference in reflected wave in saturated and unsaturated water section of soil. And the piping leakage passage position was determined which provided scientific basis in making the reinforcement scheme.
