Large long-term settlement occurs at the municipal solid waste landfills over an extended period of time which may
lead to breakage of the geomembrane, damage of the cover systems, other protective systems or facilities constructed on top of
a landfill. Also, municipal solid waste is an extremely heterogeneous material and its properties vary over location and time
within a landfill. These material characteristics require the formulation of a new constitutive model to predict the long-term
settlement of municipal solid waste. The paper presents a new constitutive model which is formulated to describe the
mechanical behavior of municipal solid waste. Model is based on Modified Cam Clay model and the critical state soil mechanics
framework incorporating time-dependent components: mechanical creep and biodegradation of municipal solid waste. The
formulated constitutive model is optimized and defined with eight input parameters: five Modified Cam Clay parameters, one
parameter for mechanical creep and two parameters for biodegradation of municipal solid waste. Thereafter, the constitutive
model is implemented in the software suite for finite element analysis (ABAQUS) and numerical analysis of the experimental
landfill settlement is performed. The proposed model predicts the total settlement which is in good agreement with field
measured settlement at the experimental landfill.
