摘　　要：利用两检测电极间充满渗出液时电阻发生突变的特点,成功地设计出具有高可靠性的HDPE膜数据采集电路。结合软件方法准确地判断HDPE膜的渗漏,再结合渗出液的化学成份来判断渗漏的种类。利用TC35I模块进入GSM网通过Internet进行数据的交换,实现了危险物贮存库渗漏的网络化监测。利用HDPE膜的绝缘性和贮存库中电场分布特点,提出偶极子的漏洞定位方法,成功解决了漏洞定位的问题。该方法为填埋场HDPE膜铺设过程中的施工验收提供了参考。A data acquisition circuit with high reliability was implemented on the basis of sudden change of electric resistance （caused by the liquid between the electrodes） as indication of HDPE leakage. Using TC35I module to access GSM, an Internet based data exchange system can be achieved. Therefore, realize network monitoring of leakage in hazardous water impoundments. The author also puts forward a successful method of locating leakage and points out the relation among the voltage of the electrometer, the size of the leakage, the interval between the dipoles, the electric resistance rate of the water impoundment and the supply power. This method will provide references for construction and quality control in laying HDPE liner in landfill.
