| 摘 要： | 在垃圾填埋场中,利用土工膜的电绝缘性来实现其施工验收和填埋垃圾期间的渗漏检测以防止污染地下水.笔者研究了漏洞大小、偶极子的位置、偶极子的电极间距、供电回路电极的位置以及填埋场内物质的电阻等对检测信号强弱的影响,并指出在多洞的情况下,偶极子的电极间距必须小于两漏洞间的距离才可确定定位漏洞.

| Abstract: | Because geomembrane is an electrical insulator,leaks on geomembrane liners can be detected when geomembrane liners are inspected insuring intact construction and when wastes have been stacked on them in the landfill.The authors studied effects on detection results caused by leak sizes,locations of dipoles,electrode spaces of dipoles,electrode locations of power supply circuit and waste resistance.It was showed that if there are many leaks,they can be detected successfully only when electrode spaces of dipoles are less than the distance between two leaks. |
