黏土的真三轴不排水剪切试验

True Triaxial Undrained Shear Tests of a Clay Sample

对广州原状结构性粉质黏土进行了在等应力比加载条件下的固结不排水真三轴剪切试验,引入一个新的概念中应变比系数bε,分析了结构性粉质黏土在该条件下的力学和变形性质。

A series of true triaxial shear tests of Guangzhou structured natural silty clayey samples are tested with consolidated undrained shear with an equivalent stress ratio. A new parameter, called equivalent strain ratio, b , is introduced in this paper, in order to characterize the mechanical properties of this structured silty clayey samples under similar conditions.
