| 摘 要： | 双衬层填埋场采用电法进行渗漏检测时,漏洞电流大小、检测电极与防渗层之间的距离、介质的电阻率以及供电电极的位置皆可影响检测效果。分别对以上几个因素进行了仿真分析,结果显示:漏洞电流越大、检测电极距防渗层越近、供电电极与漏洞的水平距离越远,检测效果越好;而渗滤液污染导致的局部土壤电阻率变低,则使检测效果变差。 |

| Abstract: | Factors including leak current,distance between detecting electrodes and impermeable liner,medium resistivity and power supply electrode location can affect the leak detection of hazardous waste landfill using electric method.The simulating results showed that bigger leak current,nearer distance between detecting electrodes and impermeable liner,farther distance between power supply electrode and leak have positive effect on detection.Local lower soil resistivity caused by leachate has negative effect on de... |
| Keywords: | landfill high density polyethylene liner leakage detection induction potential |
