级配对砂泥岩混合料压缩特性的影响
|
摘要
为了研究颗粒粒径对砂泥岩混合料压缩特性的影响,在一定的砂泥岩比例、干密度以及含水率的条件下,采用杠杆式压缩固结仪对5种不同试验级配下的砂泥岩混合料土样进行快速室内侧限压缩实验,得出5种级配下土样的e-p曲线和e-lgp曲线,并计算出土样的孔隙比、压缩系数、压缩指数等压缩指标.探讨了砂泥岩混合料压缩特性与颗粒粒径的关系,分析了试验土体颗粒级配特征值对砂泥岩混合料压缩特性的影响,为实际工程应用提供了参考依据.
In order to study on the effect of particle size of Sandstone- mudstone particle mixture on compression properties,under the determined proportion of Sandstone- mudstone particle mixture,dry density and water content,we used five kinds of gradation of Sandstone- mudstone particle mixture with confined compression test in lab with lever- type compression consolidometer,and obtained five kinds of gradation of e- p curve and e- lgp curve,calculated viod ratio,compressibility and compression index etc. We studied on the relationship between compression properties of Sandstone- mudstone particle mixture and particle size,and analysed the effect of particle gradation eigenvalue of Sandstone- mudstone Particle Mixture on compression properties,then provided reference for the application in future engineering.
