摘　　要：主要由高密度聚乙烯(HDPE)土工膜和膨润土垫(GCL))组成的垃圾填埋场防渗系统会因各种环境条件变化而使防渗性能降低,带来二次污染风险。其中,温度升高是影响膜防渗性能的一个重要因素。但是,国内鲜有针对温度升高对HDPE土工膜和GCL防渗性能影响的研究。综述了国外关于温度升高对防渗系统防渗性能的影响,并针对由于温度升高影响防渗性能的潜在问题,提出了合理化的应对措施。Mainly consisted of HDPE geomembrane and GCL,the performance of the liner system of landfills will be affected due to the changes of surrounding environment,which poses risks of secondary pollution to the environment. Among various factors affecting performance of liner,increase of temperature is the key one. However,in China,few domestic researches were conducted focused on the impact of increase of temperature on performance of landfill liner. This paper reviewed the foreign researches concerning effect of increase of temperature on performance of landfill impermeable layer. Meanwhile,it provided some reasonable advices to deal with the potential performance-related problems caused by increase of temperature.
