摘　　要：对高密度聚乙烯(HDPE)土工格栅的光氧老化机理进行系统性的介绍;分析影响土工格栅光氧老化的外界因素,包括环境因素、安装损耗和加工方式等;同时介绍高密度聚乙烯土工格栅降解后性能的变化,从力学性能、外观变化及微观指标三方面总结其老化后的表征指标,并指出HDPE土工格栅光氧老化研究方面的不足。In this paper,the mechanisms of High density polyethylene（ HDPE） geogrids after photo-oxidation aging are introduced systematically. Analyzed the influence factors for geogrids during photo-oxidation degradation,including environment factors,installation damages and processing methods. Simultaneously,introduced performance changes in the photo-oxidation of high density polyethylene geogrids,and summarized characterization of indicators from the mechanical properties,changes in appearance and microstructure indicators. Also pointed out deficiency at aspects of research and future research issues are analyzed for HDPE geogrids.
