摘 要: 垃圾填埋堆体失稳已成为环境岩土工程研究领域面临的新问题。从垃圾填埋体变形机理、变形特征参数研究、堆体稳定性分析研究方面,分析了国内外垃圾填埋堆体的研究成果及发展趋势。分析表明:从多场耦合角度揭示复杂环境下垃圾填埋堆体的变形特征与变形机理,确定各参数间的线性非线性本构模型,包括应力、应变、降解、渗流等耦合作用下垃圾填埋堆体应力应变本构模型。通过多学科的理论与方法建立更加逼近实际情况的多场耦合模型,是未来相当一段时间内多领域学者的工作重点,可为提高填埋堆体失稳控制水平提供理论基础。

Abstract: The unstability of landfill pile has become a new problem in the research field of environmental geotechnical engineering. According to the mechanism of landfill deformation, the study on the characteristics of deformation parameters and the analysis of pile body stability, the research status and development trend of the stability of landfill at home and abroad were analyzed. The analgsis shows that the focus of many scholars in a considerable period of time will be the following: revealing the deformation mechanism and deformation characteristic of landfill under complex environment from multifield coupling angle, determining the linear and nonlinear of the parameters in constitutive model which contain stress, strain, seepage and degradation, establishing the coupling model that are more closer to the actual situation through the multi-disciplinary theory. This may provide theoretical basis for enhancing the control level of the unstability of landfills.
