风化岩填料的压实变形特性试验研究

摘要

采用大型压缩仪对风化岩填料进行了系统试验,研究了三种不同结构状态填料的压实变形特性,分析了加载方式对压缩试验结果的影响,探讨了水—荷载耦合作用下填料的压实变形机理,解释了现场采用风化岩填料修筑的施工便道会在降雨后一段时间内产生较大沉降变形的原因。%This paper systematically testifies the mantle rock packing by applying large-scale compressor,studies the compaction deformation characteristics of three kinds of structural packing,analyzes the impacts of loading method on compaction testing result,and explores the compaction deformation mechanism of packing under coupled water-loading action,and finally explains the cause of settlement and deformation of construction road packed with mantle rock after raining.
