Abstract: For municipal solid waste (MSW) embedded in shallow depths within landfills, its temperature is susceptible to atmospheric temperature fluctuations that exhibit periodic change. Impact of temperature cycles on the volume change behavior of MSW remains unknown, the latter impacts the long-term stability of landfills and its further utilization as land resources. To address this issue, temperature-controlled triaxial tests are conducted to examine the temperature-cycling effect on the volume change behavior of both fresh and aged MSW under different stress levels. The test results indicate that temperature-cycling- induced elastic and plastic volume changes of MSW are much larger than those of clayey soils. The accumulated plastic volumetric strain appeares to increase with the number of temperature cycles and gradually stabilizes. The temperature-cycling induced volume change of MSW was dependent on stress level and MSW age, fresh MSW under a lower stress tended to yield a larger volume change. Neverthelexs, temperature-cycling induced volume change of the aged MSW is still significant and cannot be ignored. Based on the triaxial test results, a method is proposed to estimate the thermoelastic-plastic compression index λ_T and thermoelastic compression index κ_T of MSW. A thermo-elastoplastic constitutive model in the form of λ_T and κ_T is developed, incorporating the number of temperature cycle, stress level, and MSW age. The feasibility of the proposed model is validated against the experimental results.
