中文摘要：
陈垃圾土是一类非常特殊的土,结合重庆一封场六年多的填埋场,对陈垃圾土的物理指标,工程力学性质进行实验研究。总结了陈垃圾土的主要组成成分,得出了陈垃圾土的含水率,密度和孔隙比的具体范围,并与新鲜垃圾作了比较。探讨了垃圾各组分对土体各物理指标的影响。深入研究了陈垃圾土的三轴应力应变曲线特征,并把曲线划分了四个阶段,分析了各个阶段的特点,阐述了其产生的原因。指出陈垃圾土是具有一定的结构,但结构性很弱的土体,3σ是强度形成的主要原因。同时探讨了陈垃圾土有机物纤维,土体颗粒对陈垃圾的C,φ值影响。
英文摘要：
Stale waste is a type of soil which is different from other soil types.In order to study both the physical index and the engineering characteristics of stale waste,physico-mechanical tests were done for many groups of stale waste from one landfill in Chongqing,P.R.China that had been closed for over six years.Some basic physical indexes of the waste,such as the composition,water content,density and pore ratio,were obtained.The influence of the wastes composition on these indexes is discussed in detail here...
