摘　　要：介绍了某填埋场截污坝坝基和坝体的防渗措施,分析了调节池蓄水后截污坝发生渗漏可能存在的问题,利用物探、钻探和水质分析等技术手段,查明渗漏发生在混凝土芯墙和放空管接合部位,采用化学注浆和粘土填缝相结合的方法进行处理,取得了较好效果。The anti-seepage measures for the foundation and body of pollutant interception dam in a sanitary landfill site were presented. The possible problems due to seepage of the pollutant interception dam after water storage in regulation tank were analyzed. By using the technical measures such as geophysical prospecting, drilling, and groundwater quality analysis, it was found that the seepage came from the joint of vent pipe and concrete core wall. The chemical grouting and joint filling with clay soil were adopted to stop the seepage, and a good result was obtained.
