垃圾填埋场是城市生活垃圾处置的主要场所之一，目前的垃圾填埋场处置体系面临着诸多问题。例如，渗滤液过多是导致垃圾填埋场不稳定的重要因素。了解城市固体废物的渗透特性是环境岩土工程领域的一个相关课题。本文对城市固体废物渗透特性的研究现状进行了探讨。回顾最近的研究表明，该领域的研究根据所采用的实验方法分为两类：现场测试和实验室测试。本文总结了侧重于渗透性特征的不同研究中的测试方法、垃圾填埋场位置、废物年龄、干密度和渗透系数。此外，还对新鲜城市固体废物在不同有效应力和压缩次数下的压缩性和渗透特性进行了实验研究。此外，还得到了渗透系数与有效应力以及干密度之间的关系，并建立了渗透率预测模型。最后，对比了现有文献和本文的实验结果，总结了有效应力和干密度对城市生活垃圾渗透特性的影响。本研究为垃圾填埋场渗滤液产生分析提供依据。
A landfill is one of the main sites for disposal of municipal solid waste and the current landfill disposal system faces several problems. For instance, excessive leachate water is an important factor leading to landfill instability. Understanding the permeability characteristics of municipal solid waste is a relevant topic in the field of environmental geotechnical engineering. In this paper, the current research progress on permeability characteristics of municipal solid waste is discussed. A review of recent studies indicates that the research in this field is divided into two categories based on the experimental method employed: field tests and laboratory tests. This paper summarizes test methods, landfill locations, waste ages, dry densities and permeability coefficients across different studies that focus on permeability characteristics. Additionally, an experimental study on compressibility and permeability characteristics of fresh municipal solid waste under different effective stresses and compression times was carried out. Moreover, the relationships between the permeability coefficient and effective stress as well as dry density were obtained and a permeability prediction model was established. Finally, the experimental results from the existing literature and this paper were compared and the effects of effective stress and dry density on the permeability characteristics of municipal solid waste were summarized. This study provides the basis for analysis of leachate production in a landfill.
