摘要
根据多孔介质渗流力学和热力学理论,从填埋场内非等温的角度分析了填埋场内水分运移与温度变化之间相互作用的机理;在综合考虑垃圾填埋场温度场与渗流场耦合的基础上,建立了垃圾渗滤液运移的双场耦合连续介质数学模型,并给出了求解该数学模型的有限元方法。为研究垃圾渗滤液在填埋场中的运移状况以及控制系统的设计、管理提供了可靠的理论依据。
Based on the theoretical mechanics of porous seepage and thermodynamics, from the non-isothermal angle, the coupled mechanism of the moisture transfer and temperature change in landfill site is analyzed. According to the analysis of coupling action between temperature and seepage field in the landfill site, the coupled double-field model for leachate transport is established, and also the finite element numerical solution method of the mathematical model is presented, thus providing the theoretical basis for the study of leachate transfer in landfill site and for the design and management of leachate control system.
