摘　　要：针对城市垃圾卫生填埋场渗滤液成分复杂、浓度高、污染性强的特点,分析了在卫生填埋场构筑防渗系统的功能要求,根据粘土固化浆液的组成特征和固化机理,研究了粘土固化注浆帷幕对渗滤液的抗渗性能和对污染物质的吸附特性,结合粘土固化注浆帷幕在卫生填埋场防渗工程中的应用实例,从施工质量检测、防渗效果监测和技术经济角度,证明了这种垂直防渗技术应用在垃圾填埋场的可靠性和经济性。Aimed at the complicacy of contaminants, high concentration, and strong pollution of the leachate in municipal sanitary landfill site, the function of anti-seepage system was analyzed. Based on the component and its solidifying mechanism of clay-solidified grouts, the penetration capacity and the adsorption characteristics of clay-solidified grouting curtain on leachate or contaminants were studied. The clay-solidified grouting curtain was adopted in an actual landfill. The reliability and economy of the vertical anti-seepage technology used in municipal sanitary landfill site were proved from construction quality, anti-seepage efficiency and techno-economy.
