Research of Stratified Compaction Process of Municipal Solid Waste

The density of municipal solid waste is lower. In order to increase the density of garbage dump, guarantee safe operation, save operational cost and extend the lifetime of landfill site it is very important to compact garbage layer by layer. Through the analysis of mechanical property and systematically study of the engineering experiment of Changshengqiao Sanitary Landfill which is the first standardized landfill site in Chongqing we conclude that there is no positive influence of compacting effect caused by moisture content of garbage dump, and the best compacting effect is resulted from 3 times compacting of each garbage layer of which the thickness is about 0.6m by special compactor.
