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 a large number of triaxial test data, the stress-strain relationship of cemented coarse grained soil under confining pressure, curing time, cement content and other factors was analyzed and compared with the stress-strain relationship of non-cemented specimen. The results show that the influence of various factors on the deformation and strength of cemented coarse grained soil is significant. Compared with the non-cemented coarse grained soil, the stress-strain curve of cemented coarse grained soil shows obvious strain softening phenomenon, and the dilatancy phenomenon Obviously, laid a foundation for determining the stress-strain relationship of cemented coarse grained soil.
