摘要
为了评估生物反应器填埋场垃圾体的压缩特性,预测垃圾体在荷载作用下的主压缩沉降,研制了一套主压缩沉降试验仪,对生物反应器填埋场主压缩沉降的室内试验进行研究,试验分为3组平行试验同时进行,日平均沉降量小于0.1 cm即为结束,3组试验结束时的主压缩沉降量分别达到了总沉降量的68%、63%和60%.试验表明生活垃圾是具有高度压缩性的材料,主压缩沉降量与初始干密度之间存在着直接的关系,同时随着荷载的增大,压缩沉降速率有减小的趋势。
A set of primary compression settlement apparatus was designed in order to evaluate the compression characteristics of bioreactor landfill and to forecast the primary compression settlement of garbage body under load.The primary compression settlement test of landfill was conducted with this apparatus in the laboratory.Three groups of parallel tests were carried out.When daily average settlement is less than 0.1 cm,which means the test is over.At the end of the test,the primary compression settlement reached 68%,63% and 60% of a total settlement respectively.The test showed that domestic garbage is of high compressibility material.There exists the direct relation between primary compression settlement and initial dry density.Simultaneously,the compression settlement rate decreases with load increasing.
