摘　　要：根据渗沥液所处的不同环境区域,从渗沥液释放传输机理及试验、渗沥液释放传输过程的耦合数值分析等方面,分析了国内外垃圾渗沥液释放传输过程的研究现状及发展趋势,结果表明:揭示物性参数间的本构关系,提出定量的计算模式;建立更加接近于真实情况的多场耦合模型;开展大变形多孔介质污染物传输多场耦合模型求解新方法研究;采用归一化数学模型,将填埋场、非饱和含水层和饱和含水层作为统一的整体进行模拟研究,将是该领域研究的重要趋势。According to waste leachate from different environmental region, research status and development trend of waste leachate release and transport at home and abroad were analyzed from two aspects, such as release and transport mechanism and experiment, and coupling numerical analysis of leachate. The results showed that revealing the constitutive relationship between physical parameters, giving quantitative calculating models, establishing the multi-field coupled models which came close to the actual situations, carrying out research on the new method for solving multi-field coupled models of contaminant transport in large deformation porous media, and simulating leachate release and transport using a normalized numerical model which takes the landfill site, the nonsaturated aquifer and the saturated aquifer as an unified whole, will be the important development trend in this research field.
