摘　　要：对城市垃圾场有害液体通过渗漏污染地下水问题的解决已迫在眉睫,而目前对垃圾场有害液体渗漏监测的方法存在各种问题,传统的环境地球物理的方法是垃圾场有害液体渗漏监测的主要手段之一,但该方法存在监测范围少,时间间隔长的缺点。介绍了垃圾渗漏污染的基本机理和使用环境地球物理电阻率法监测渗漏的原理,通过引用了一个数据模拟的例子对比全通道方法与其他传统方法,表明了全通道方法明显的优势。同时讨论了使用永久埋地电极进行数据采集和处理的优点,并且提出该监测方法分阶段的数据处理和解释的主要思路和原理。针对垃圾场的极大市场规模,采用全通道电阻率法作为数据采集方案,可有效对垃圾场进行实时、高效、全方位的监测,可在全行业范围内推广应用。The groundwater pollution resulting from landfill leakage in urban areas has become an increasingly serious threat. At present,there are various problems in the method of monitoring the landfill leakage. The environmental geophysics methods are the main approaches for leakage monitoring. However,similarly to other landfill leakage monitoring methods,these traditional geophysical methods have the problems of limited surveying range and a long period of survey intervals. This paper introduces the elemental mechanism of landfill leakage pollution,whilst also reviewing the principles of applying resistivity method to monitor leakages. The resistivity Full Channel Method is introduced with apparent advantages; these are illustrated using a synthetic model to compare the Full Channel Method against other traditional methods. This paper also discusses the advantages of using permanent buried electrodes for data acquisition,and processing,while introducing the main methodologies and principles of the data interpretation on the resistivity anomaly. With the extensively large scale of the landfill industry,the data acquisition and processing with resistivity Full Channel Method can provide real-time,high-efficiency,and comprehensive monitoring,which deserves to be applied within all landfill sites.
