| 摘 要： | 利用高压直流电法对双人工合成衬层间加粘土层和土工导水网2种模拟填埋场渗漏定位进行试验研究.结果表明:对上层膜检测时,第2种模拟填埋场的总回路电阻比第1种的约大15%;对下层膜检测时,第2种模拟填埋场的总回路电阻比第1种的约大20%.利用高压直流电法,2种模拟填埋场都可以较好地进行漏洞定位,在电极间距为1m时,漏洞定位误差不超过10cm. |

| Abstract: | Two types of double high density polyethylene(HDPE) liners landfill that clay or geogrid was added between the two HDPE liners. The general resistance of the second mode is 15% larger than the general resistance of the first mode in the primary HDPE liner detection,and 20% larger than that of the first one in the secondary HDPE liner detection.High voltage DC method can accomplish the leakage detection and location of these two types of landfill and the error of leakage location is less than 10cm when electrode space is 1m. |
| Keywords: | landfill leak location clay geogrid |
