摘　　要：粘性土隔离层不仅具有防渗作用,还有截污作用。基于利用这种截污作用,把废物处置场的衬垫层“禁止渗滤液向地下水中渗漏”的理念转变为“隔离污染物,可允许水进入地下水”,提出了一种新的废物处置场地下水污染控制的理论方法,探讨了地下水含水层之上的“有效隔离层足额厚度”、“截污容量”等处置场阻隔层特性新的参数的实验测试和计算方法。以北京平原区城市垃圾处置场规划区选定为例,实际应用了这种新理论方法。It has been recognized that clayey soil can not only prevent underground- water from pollution by seepage, but also exhibit plugging up contamination from various wastes. Therefore, it is an innovation for control of pollution on groundwater in waste landfill through a translation of from the theoretics named as “ prevention of infiltrate into groundwater” to “ insulating waste, allowing water into groundwater” . Based on this, a new theory of preventing waste landfill from pollution to groundwater is presented in this investigation. If we could make a utilization of its filtration adequately, just as using a trial in laboratory to research the filtration capability, calculation, we could made new testing technique and calculated technique of liner parameters. In the present paper, we take an example as a pilot test, which calculates liner parameters, such as “ filtration capability” and “ adequacy thickness of effective liner” , and makes a programming of landfill site by this theory and method in Beijing plain.
