摘　　要：近年来,我国遗留场地重金属复合污染问题日益突出。为有效阻断重金属迁移扩散,阻隔技术成为国内外场地污染控制研究的焦点。通过系统分析阻隔技术在典型重金属污染场地的应用实例,概述阻隔技术先进材料和相关实施现状,发掘不同阻隔技术应用过程中的主要问题,提出了阻隔技术组合式应用和阻隔系统工程决策等研究方向,从技术、经济、土地再利用等多维度综合考量,为复杂情景下的场地重金属污染治理提供理论依据和技术参考。In recent years,the problem of combined pollution of heavy metals in the left contaminated sites in China becomes increasingly prominent.In order to effectively block the migration and diffusion of heavy metals,barrier technology has become the focus of site pollution control at home and abroad.In this study,we systematically analyzed typical application examples of barrier technologies in heavy metal contaminated sites,and then we summarized the current situation of advanced materials and correlated construction methods of barrier technologies,to explore the main problems of different barrier technologies in the process of application.At last,we put forward popular research directions,including combined application of different barrier technologies and engineering decision-making of barrier system application,in the respects of technology,economy and land reuse,so as to provide theoretical and technical references for heavy metal pollution control in complex scenarios.
