  • 摘要: 在半干旱地区，利用腾发盖层代替传统盖层，在相同的防渗效果下可以减少垃圾填埋场设计过度造成的浪费。以兰州地区为例，实验测试得到兰州黄土的土水特征曲线，求得田间持水量和萎蔫含水量；结合兰州地区2007—2008年气象资料，利用Hydrus-1D软件，模拟了透过盖层的降水入渗量，分析了黄土盖层替代传统盖层的可行性。研究结果显示，31 cm厚的黄土盖层理论上可以满足阻止降水入渗的要求，与传统盖层相比，具有成本低、施工简单的优点。
    Abstract: In semi-arid area, the disposal cost can be reduced if the traditional standard cover for the landfills is replaced by the evaportranspiration (ET) cover at the same rainfall penetration. In this study, the soil water characteristic curve of Lanzhou loess was tested to obtain the field capacity and wilting coefficient in laboratory. Simulation was performed by Hydrus-1D software to evaluate the percolation of rainfall through the cover, combining with meteorological data in Lanzhou area in 2007—2008. Based on this, the feasibility of ET cover was evaluated. The results showed that 31 cm thick loess cover can prevent the infiltration of precipitation theoretically. Compared with traditional standard cover, evaportranspiration cover has the advantage of low cost and easy construction.
