摘要
轻量化处理方法是疏浚淤泥的再生资源化处理方法之一,在国际上得到了越来越广泛的关注和认可。作为轻质填土材料中的一种,疏浚淤泥EPS颗粒轻质土的压缩变形特性及沉降计算值得关注。在等向压缩试验基础上,分析了EPS颗粒添加量、水泥添加量、养护龄期对轻质土试样的压缩曲线、结构屈服应力、压缩参数等的影响规律,并给出了最终沉降量计算公式。
The technologies of regenerating dredged silt into geotechnical construction materials have received more and more attention internationally. One of these methods is to change the waste silts into lightweight treated soil. As one of lightweight materials, compression deformation properties and settlement calculation of lightweight soil are worth to study.The impacts of EPS beads content, cement content and curing periods on compressive curves, structural yield stress and com-pressive parameters are analyzed with the isotropic compression test. Finally, Settlement calculation formulas are discussed.
