MBT（Mechanical-Biological Treatment）垃圾处理技术具有资源化、无害化、减量化的优点，可以有效减少垃圾的填埋量，因此，MBT垃圾的处理已成为环境岩土工程领域研究的热点课题之一。本项目采用理论分析、数值模拟、室内渗透试验、模型槽试验及现场试验相结合的研究方法，模拟MBT垃圾渐进填埋堆高过程，考虑组分、尺度、压力、压缩时间、温度、水力梯度、渗滤液浓度等多因素影响，对MBT垃圾渗透与变形的相关性进行系统地研究，建立基于变形相关性的MBT垃圾渗透系数预测理论模型，进一步解释MBT垃圾渗透与变形相互作用机理，编制有限元程序进行数值模拟，制定MBT垃圾渗透与变形相关试验标准。本项目研究，可以有效解决“垃圾围城现象”、进一步促进岩土工程与环境工程学科交叉，为MBT垃圾填埋场稳定性分析、渗滤液产量估算及渗滤液导排系统设计奠定理论基础。因此，本研究将具有重要的社会和环境意义。

MBT (Mechanical-Biological Treatment) has the advantages of resource utilization, harmlessness, and reduction, which can effectively reduce the amount of landfill. Therefore, the treatment of MBT waste has become a hot topic in the field of environmental geotechnical engineering. This project adopts the research method combining theoretical analysis, numerical simulation, laboratory test, model tank test and field test to simulate the process of MBT waste progressive landfilling, considering the effects of component, scales, pressure, compression time, temperature, hydraulic gradient, leachate concentration and other factors. The correlation between permeability and deformation was systematically studied, and the theoretical prediction model of permeability coefficient was established to further explain the interaction mechanism of permeability and deformation. The finite element program was compiled for numerical simulation, and the MBT waste permeability and deformation related test standards were formulated. The research of this project can effectively solve the “garbage siege” and further promote the interdisciplinary of geotechnical engineering and environmental engineering. The project will lay a theoretical foundation for the stability analysis of MBT waste landfill, leachate production estimation and the design of leachate drainage system. Therefore, this study will have important social and environmental protection significance.
