地下防渗墙快速无损检测技术研究

通过对防渗墙的成墙机理与防渗墙和周围介质存在的物性差异入手，从技术背景、技术原理和适用情况等方面分析研究了适合地下防渗墙质量检测的技术。运用探地雷达、高密度电法和瑞雷面波法三种方法对分沂入沭的堤防防渗墙进行现场检测，从不同检测技术得出的资料数据分析了防渗墙存在的质量问题，并与钻孔取芯的实际检测结果比对分析。对三种探测技术进行了综合评价，得到了适合防渗墙快速无损检测的技术，即利用探地雷达和高密度电法进行防渗墙的快速无损检测，其检测的结果是有效和准确的。

Quick Non-damage Inspection Technique for Underground Impervious Curtain

According to the formation mechanism of impervious curtain and the physical differences between the curtain and surrounding medium, this paper researches the inspection technique adaptable for embankment impervious curtain from the technical background, technical principle and adaptability, etc. Three methods were adopted for site inspection of embankment impervious curtain, the results of which were compared with those from core boring test. According to the comprehensive evaluation result of the three inspection methods, a quick non-damage inspection technique adaptable for impervious curtain, i.e. quick non-damage inspection using ground radar and high-density power, was recommended. The inspection result of this method is more accurate.
