Abstract: In order to investigate the long-term deformation properties of municipal solid waste (MSW), a series of creep- decomposition comparative tests were conducted in the laboratory under different biodegradation conditions. Based on the experimental results, characteristics of strain changing, void ratio changing, settlement rate changing against time, and the relationship between stress and strain of MSW were studied. The logarithmic settlement rate is linear with respect to the logarithmic time considering degradation of MSW. It can be concluded that the creep properties of MSW is not related with stress but also with decomposition of organic fraction by considering the stress-strain curve. Test results have proved that the creep-decomposition experimental test offered a new method for investigating the deformation properties of MSW in laboratory.

Key words: municipal solid waste, biodegradation, creep deformation properties, settlement rate
