| 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,理论上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.推导了渗流场与温度场控制方程,并建立了渗滤液运移的双场耦合数学模型.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.

| Abstract: | Based on the theory of mechanics of porous medium seepage and thermodynamics, from the non-isothermal angle, the interaction mechanism between the moisture transfer and temperature change in landfill site is analysed theoretically in the paper. The equations governing temperature field and seepage field are derivated, and a coupled double-field model for seepage transport is established, providing theoretical basis for the study of leachate transfer in landfill site and for the design and management of leachate control system. |

| Keywords: | landfill leachate temperature field seepage field coupling governing equation |
