摘要
介质的非均质性和各向异性导致填埋场渗透率跨越好几个数量级,加之目前还没有足够先进的检测手段对填埋场内部进行观测,渗透率很难准确确定,同时刻意追求其精确值也是与现实不符的。本文通过对填埋气运移规律的分析,基于模糊渗流理论建立了垃圾填埋气运移的数学模型,并利用模糊结构元的方法得到一维理想模糊渗流问题的解析解。这为填埋气控制系统的设计以及环境影响预测和评价提供了理论依据,为研究煤层气、石油污染等地下渗流问题开辟了一条新的途径。
Because of heterogenous and anisotropic medium, the seepage rate of landfill site varies greatly, and now there is no feasible means enable to observe the internal state of the landfill. It is more difficult to define the seepage rate and doesnot match the fact. This paper gives the mathematical model of landfill gas based on the fuzzy seepage theory, and get the analytic result by use of fuzzy structuring element. It provides basis for designing landfill gas control system and evaluation of environment, finds a new way for study of underground seepage problem such as mine gas and oil contamination.
