Reliability Analysis of Municipal Solid Waste Settlement
It is well-known that the disposal of municipal solid waste (MSW) has become one of the challenges in landfill engineering. It is very important to consider mechanical processes that occur in settlement response of MSW with time. In the recent years, most of the researchers carried out different tests to understand the complex behavior of municipal solid waste and based on the observations and proposed different models for the analysis of stress-strain, time-dependent settlement response of MSW. However, in most of the cases, the variability of MSW is not considered. For the analysis of MSW settlement, it is very important to account for the variability of different parameters representing primary compression, mechanical creep, and effect of biodegradation. In this chapter, an approach is used to represent the complex behavior of municipal solid waste using response surface method constructed based on a newly developed constitutive model for MSW. The variability associated with parameters relating to primary compression, mechanical creep, and biodegradation are used to analyze MSW settlement using reliability analysis framework.
