Твердые бытовые отходы (далее ТБО) занимают значительные площади урбанизированных территорий. Поведение свежих бытовых отходов характеризуется выраженным деформационным упрочнением и аналогично напряженно-деформи- рованному состоянию псевдосвязных неводонасы- щенных грунтов, армированных произвольно ориентированными волокнами. Особенностью ТБО является преимущественная ориентация армирую- щей компоненты в одном горизонтальном направ- лении, что связано с технологией укладки мусора на полигонах депонирования. В первые десятилетия после закладки на хранение в толще ТБО протека- ют процессы химического и биологического разло- жения. После их окончания отходы классифициру- ются как свалочный грунт с крупностью частиц не более 20 мм. С развитием процессов биологическо- го разложения деформационное упрочнение ТБО под нагрузкой снижается.

Municipal solid waste (further MSW) occupy considerable sites of urban territories. Behaviour of “fresh” MSW is characterized by deformation hardening similarly to stress-strain state of pseudocohesive unsaturated soils reinforced by randomly oriented fibers. Distinctive feature of MSW is predominant orientation of reinforcing component in one horizontal direction, which is associated with the technology of waste deposing on the landfills. During first decades after placement processes of chemical and biological decay proceed in waste massif. After their completion MSW are classified as waste soil with maximal particle size not more than 20 mm. With the progress of biodegradation deformation hardening of MSW under loading is decreasing.
