| 摘 要： | 土工膜的渗漏检测及补漏处理是填埋场功效保障的重要措施。通过对国外填埋场渗漏检测的多种方法的比较,成功研制了基于高压直流电法的渗漏检测系统。该系统解决了由于填埋场检测面积大所带来的采集数据量大、传输距离远的问题。通过建立合理的地电模型,解决了非均匀介质条件下电势分布问题,进而提高了系统的检测精度。通过杭州的实验检验,结果表明该系统在检测电极间距为4m时,误差超过0.4m的概率低于10%。

| Abstract: | Leakage detection is the most important step for assuring landfill performance. A new leakage detection system based on high voltage DC method was successfully developed through comparison of various methods. The system successfully shoots the difficulties of massive data collection and long distance transmission caused by spreading detection area through setting up a reasonable earth-electricity model for the target to resolve the distribution of electrical potential in even mcdium and improve the detection accuracy. Field tests in Han-gzhou shows the system detection error probability is no more than 10% with error over 0. 4m when space between detection electrodes is 4m. |
