Abstract

In order to discover the deformation characteristics of MSWI (Municipal Solid Waste Incineration) bot- tom ash,the material characteristics were analyzed,and consolidated triaxial draining compression tests were car- ried out for the samples with various particle size distribution and immersion time as well as for the remoulded sam- ples after destruction.Thus,the stress-strain curves and effective stress ratio curves of MSWI bottom ash at diffe- rent confining pressures were obtained.The results show that (1) particle size distribution and immersion time are two important factors influencing the deformation characteristics of MSWI bottom ash; (2) for the samples with a particle size being less than 2mm,the strength decreases as the content of large-size particles increases and slightly decreases with the prolonging of immersion time; (3) the strength of remoulded MSWI bottom ash decreases after the destruction; and (4) in comparison with that of the standard sand,the peak of stress-strain curve of MSWI bot- tom ash appears relatively faster.

Key words： municipal solid waste; bottom ash; particle size distribution; immersion time; confining pressure; con- solidated draining compression test
