| 摘 要： | 基于同一孔隙比条件下的结构性土抗压应力p与相同密度和含水量条件下的重塑土(非结构性土)的抗压应力pr不同,定义结构性参数r=plpr.将结构性参数r引入剑桥模型,建立了新结构性剑桥模型.通过黄土的常规三轴排水压缩试验,结果证明了剑桥模型能够合理地描述结构性黄土的基本力学特性.

| Abstract: | At the same void ratios,the compressed stresses"p"of structured soils are different from the compressed stresses"pr"of de-structured soils with the same density and water content,so we defined the structured parameter"r=p/pr".Then we set up a new structured Cam-clay model by introducing the parameter"r"into Cam-clay model.Finally,through the result of three axle draining water compressive test of loess,we proved the new model can reasonably describe the basic mechanics characteristic of loess. |
