Laboratory Measurements of K0 of Municipal Solid Waste
Laboratory measurements of the coefficient of earth pressure at rest,K0,of municipal solid waste were made in a large-scale testing device using tactile pressure sensors.The effects of waste composition,compaction and overconsolidation ratio(OCR)on the coefficient earth pressure at rest,K0 of municipal solid waste were evaluated.The tests results showed that K0 of municipal solid waste decreased with increasing fiber content and OCR of the waste.K0 decreased at first with increasing of applied vertical stress and then became approximately constant value at 0.48,0.35,and 0.23 for MSW 100%< 20 mm,MSW 65%< 20 mm and MSW 35%< 20 mm respectively.Compaction effort also affected the initial value of K0.However,with increasing vertical stress the effect of compaction decreased and was finally eliminated.
