摘　　要：利用基于双电极法的偶极子检测和基于电极栅格法的区块化检测装置,对重庆某生活垃圾填埋场进行了防渗层高密度聚乙烯(HDPE)膜完整性检测.结果表明:偶极子在漏洞附近时,其周围电势分布会出现正负突变;区块化检测利用网格铺设电极和上位机软件解析可以精确定位漏洞位置.基于高压直流电法的便携式渗漏检测系统,在填埋场铺设防护层的条件下能够有效地检测到直径约1cm的漏洞,并且能够对漏洞进行精确定位.对2种不同电学方法的验证表明,电极栅格法比双电极法测量范围大、精度高.This article briefly introduces the importance of landfill liner leakage detection. The portable leakage detection system was applied to detect HDPE integrity in a Chongqing municipal landfill. Two detection methods were used during inspection; one was dipole detection based on the dipole electrodes technique and the other was regional fast detection based on the electrode grid technique. On-site experimental results showed that a polarity change occurred when the dipole detection system located a leakage. The leakage was precisely located when using the regional fast detection system. The results also showed that the portable leakage system can precisely locate HDPE holes less than 1 cm. Compared with the dipole electrode technique, the electrode grid detection technique is more precise and faster.
