比较了垃圾填埋场衬垫系统的一些最低设计要求，并通过二维（2D）污染物迁移分析研究了几种日本衬垫系统的性能。我们证明(1)日本厚生劳动省（目前为厚生劳动省）规定的每个系统的性能各不相同；(2)矿物屏障的吸附特性对污染物的运输过程有显著影响；(3)屏障系统中的土工膜层在降低垃圾填埋场地下地下水中污染物的峰值浓度方面非常有效，即使土工膜有许多缺陷。在此条件下，分析结果表明，应避免没有土工膜层的衬砌体系。
Some minimum design requirements for landfill liner systems were compared, and the performance of several Japanese liner systems was investigated by two-dimensional (2D) contaminant transport analysis. We demonstrate that (1) the performance of each system specified by the Japanese Ministry of Health and Welfare (at present the Ministry of Health, Labor, and Welfare) varies, (2) the adsorption characteristics of the mineral barrier has a significant effect on the contaminant transport process, and (3) a geomembrane layer in the barrier system is very efficient in reducing the peak concentration of contaminants in the groundwater beneath a landfill even if the geomembrane has a number of defects. Under the conditions considered, the analysis results show that a liner system without a geomembrane layer should be avoided.
