  • Abstract:
  • Cities generate large amount of municipal solid waste daily. MSW if not disposed property can be very harmful for environment and causes soil, water and air pollution. Landfilling is most popular technique for waste disposal and widely adopted in India. For successful operation of landfills and to design landfill and its components, solid waste properties are required. Settlement and slope stability are two important parameters that decide the design life of a landfill. In current study, various engineering properties of fresh MSW obtained from bharwara sewage treatment plant site are evaluated. Experimental program includes behaviour assessment of MSW through gradation, specific gravity, compaction, compressibility (primary and secondary compression), hydraulic conductivity, and shear strength. The primary focus of experimental work was to obtain settlement and strength parameters of fresh MSW. Based on obtained properties, numerical analysis was performed using soft soil creep (SSC) and Mohr Coulomb (MC) material models to obtain the settlement and slope stability of a typical landfill. Settlement was also calculated by an analytical method and compared with numerical result. It was found that settlement calculated by modelling MSW using MC material model was found to be significantly less compared to SSC material model. Reason for the lesser value of settlement in MC model is primarily due to the negligence of secondary compression or creep. Settlement obtained by the analytical solution was found to be comparable with the numerical study performed using SSC model. Reduced slope stability was observed as landfill height increased. Settlement and slope stability analysis was performed after providing landfill cover and more settlement and less slope stability was found for covered landfill compared to uncovered landfill.
