In this stud, using landfill covers with different physical properties such as compaction levels or moisture conditions, laboratory experiments for understanding gas transport characteristics were conducted. By combining the obtained results from the laboratory experiments with literature data for mass and heat transport parameters for variably-textured soils, unified predictive models for mass and heat transport parameters were proposed, which enable to simulate gas, solute, heat transport in landfill covers with different physical properties.

在这项研究中，使用不同的物理性质，如压实水平或水分条件下，填埋场覆盖物，进行了实验室实验，了解气体传输特性。将室内实验结果与变质地土壤的质量和热量运移参数的文献数据相结合，提出了质量和热量运移参数的统一预测模型，该模型能够模拟不同物理性质的填埋场覆盖层中气体、溶质和热量的运移。
