摘要: 基于多孔介质流体力学、多相流以及土壤水动力学理论,利用理论分析和数值模拟相结合的方法,研究了垃圾填埋场中渗滤液运移过程的基本规律,并对填埋场底部可渗和不可渗2种情况下渗滤液的运移规律进行了模拟比对,研究成果可为填埋场渗滤液控制系统的设计和管理提供科学的理论依据和技术支持。Abstract: Based on the theories of fluid mechanics, multiphase fluid mechanics and soilwater dynamics in porous medium, the characteristic of leachate transportation process in landfill was studied by combining the theoretical analysis with numerical simulation in this paper. The transportation in the situation of leakage and non-leakage for the bottom of landfill is compared by numerical simulation. The results can provide theoretical evidence and technical supply for design and management of leachate controlling system in landfill.
