两种重塑土样的结构性差异试验分析
Laboratory Study on Structural Performance of Two Reconstituted Soil Samples
摘要
Abstract
Natural clays are generally structural clays, and reconstituted soil samples also have some structural char-acteristics due to different sample preparation processes. Structural reconstituted soil samples are usually used in la-boratory studies, and the sample preparation conditions have great influences on samples’ structural characteristics. Two kinds of reconstituted soil samples ( with the same size, soil type, dry density, and moisture content, yet with different saturation methods) were prepared and the structural characteristics were analyzed by uniaxial compression and uniaxial loading-unloading compression tests. It was found that vacuum suction saturation could weaken the structures and uniformities of reconstituted soil samples, and the soil samples without vacuum suction saturation had very good initial uniformity and typical structural characteristics.关键词
