Effect of the spatial changes in engineering properties on municipal solid waste landfill slope stability
Landfill is the main method for disposing of municipal solid waste (MSW). However, landfill instability destruction accidents occur frequently, and the instability is influenced by multiple factors. Due to the complex composition of MSW and its obvious heterogeneous properties, landfill stability is the most significant engineering challenge in landfill operations. This paper has provided a review about status quo of MSW disposal and researched the impact factors of MSW landfill stability through extensive literature research. In view of the landfill process and specific heterogeneity of MSW, a finite element model about spatial changes in engineering properties on MSW body has been proposed. Then the sensibility analysis of the engineering properties on heterogeneity municipal solid waste body stability has been conducted, and the influence curves for the safety factors of the MSW body have been proposed. Finally, suggestions have been proposed that can provide technical support and can serve as a reference for the design, operation, and maintenance of MSW landfills.
期刊介绍：
Engineering geology is defined in the statutes of the IAEG as the science devoted to the investigation, study and solution of engineering and environmental problems which may arise as the result of the interaction between geology and the works or activities of man, as well as of the prediction of and development of measures for the prevention or remediation of geological hazards. Engineering geology embraces:
• the applications/implications of the geomorphology, structural geology, and hydrogeological conditions of geological formations;
• the characterisation of the mineralogical, physico-geomechanical, chemical and hydraulic properties of all earth materials involved in construction, resource recovery and environmental change;
• the assessment of the mechanical and hydrological behaviour of soil and rock masses;
• the prediction of changes to the above properties with time;
• the determination of the parameters to be considered in the stability analysis of engineering works and earth masses.
