通过填埋场现场运行实验,对生活垃圾在填埋场中的压实机理进行了研究。实验结果表明,压力是决定压实效果的最重要的外在因素。垃圾在外力下的形变大体可分为三个阶段:垃圾组分之间的大空隙被填没,垃圾体不可逆蠕变,垃圾体的范性变形;决定压实效果的内在因素有垃圾组分、垃圾含水率等。另外,作业过程中垃圾堆体的摊铺厚度、机械行程次数、行驶速度和坡向及坡度等也是影响垃圾堆体压实效果的重要因素。 Through the landfill site operation experiment, the compaction mechanism of domestic waste in landfill was studied. The experimental results show that pressure is the most important external factor that determines the compaction effect. Garbage deformation under external forces can be roughly divided into three stages: large gaps between garbage components are filled, the body of the irreversible creep, the normal deformation of the body of garbage; compaction effect of the internal factors of garbage components , Garbage moisture content. In addition, the process of rubbish pile body paving thickness, the number of mechanical trips, driving speed and aspect and slope is also an important factor affecting the compaction effect of landfill.
