摘　　要：就目前有关导排层阻塞微观机理、宏观试验方面的研究进行归纳总结,发现引发卫生填埋场导排层阻塞的作用机理主要有惰性固体悬浮物沉积、微生物附着、金属离子沉淀、气体填充、界面效应影响等;在宏观上影响导排层阻塞速率的因素主要包括渗滤液特性、环境因素、导排层颗粒特性等;同时指出现有研究中存在的问题,提出了针对今后研究的方向与建议。The research status of the microcosmic mechanism and macroscopic examination that induce clogging are summarized. The microcosmic mechanism includes deposition of FSS,microbial attachment,ions precipitation,the production of gas and interfacial effects. On the macro level,the factors having influence on clogging includes leachate properties,environmental factors and the gravel properties. The existing problems are pointed out,and the focus of the future research in this field is put forward.
