摘要
在大量三轴试验资料基础上,分析了胶结粗粒土在围压、养护时间、水泥含量等因素下的应力应变关系,并与无胶结试样的应力应变关系进行对比。结果表明,各影响因素对胶结粗粒土的变形和强度影响显著,与无胶结的粗粒土相比,胶结粗粒土的应力应变曲线呈明显的应变软化现象,且试样的剪胀现象明显,为确定胶结粗粒土的应力应变关系奠定了基础。
Based on the data of triaxial test,the cemented coarse-grained soil stress-strain relationship between confining pressure,curing time,cement content is analyzed and compared with that of non-cemented samples.The results show that confining pressure,curing time,cement content have a significant impact on deformation and strength of the cemented coarse-grained soil;comparison of the non-cemented samples,the stress-strain curves of the cemented samples appears a distinct phenomenon of strain-softening and dilatancy is obvious.Thus,it provides reference for setting up stress-strain relationship of cemented coarse-grained soil.
