摘要:
简易垃圾填埋场的衬层为压实黏土,衬层的渗透率直接决定了填埋场的使用年限。通过确定渗滤液在土体中的渗透速率和范围,计算出渗滤液的击穿深度,并得到经济安全的衬层厚度,是垃圾填埋场衬层设计的主要内容。通过引入均匀化理论,推导出黏土衬层渗透率的均匀化公式,然后利用有限元软件建模分析,最后研究垃圾填埋场中衬层块度对渗透性的影响。结果表明衬层的渗透率随着块径尺寸的减小而减小,填埋场的使用年限随之延长。
Abstract:
The lining layer of the simple landfill site is compacted clay. determines The life of landfill is directly determined by the permeability of the lining layer. The puncture depth of leachate and getting the economic and safety thickness were calculated by determining leachate’s rate and scope in the clay. Based on the homogenization theory, the analysis model was established by the use of finite element software. At last the size effects of backfilling clay in landfill was analyzed. Results show that the lining of the permeability decreased with the decrease of the piece of diameter size, meanwhile, the life of usage of landfill increased.
