| 摘 要： | 对饱和黄土试样进行不排水三轴剪切试验,总结了围压、超固结比、偏压固结比对饱和黄土力学性能的影响规律。分析表明:饱和黄土的抗变形能力由两部分组成:一是结构性;二是颗粒间的摩擦。其中前者对初始变形模量的影响较大;而后者则对土体的残余不排水强度起决定作用。同时指出结构性在饱和黄土力学性能研究中的重要性。

| Abstract: | Saturated loess samples were tested by tri-axial apparatus with CU method.Three factors,including confining pressure,over-consolidated ratio and anisotropic consolidated ratio were considered to study their effects on saturated loess' mechanical performances.The results indicated that the ability of saturated loess' anti-deformation constitutes two parts,one is structural characteristics,which has relatively large influence on the initial shearing modulus;another one is friction,which determines residual un... |
