The results show that the formation of the shear band is characterized with both strain localization and the localization of the averaged pure rotation ratio. The shear band starts right at the point where the volume strain changes from shrinkage to expansion. The development of these variables are significantly different within or outside of the shear band. Particularly, the stress-strain softening relationship was observed near or within the shear band, while the hysteretic phenomenon takes place outside the shear band. In addition, both the volumetric and deviatoric strains are larger inside than outside the shear band, with the soil being looser in the shear band.

研究表明：砂土剪切带的形成过程即为试样内部应变局部化过程，也为试样内部平均转动率(averaged pure rotation rate， APR)的局部化；剪切带开始形成点也为试样剪缩、剪胀分界点；剪切带内外各宏微观参数变化规律上存在明显的差异，主要表现为近剪切带位置土体及带内土表现为应变软化现象，而距带中心较远土体应力应变关系曲线出现'回滞圈'现象；带内变形量明显大于带外，且带内较带外松散。
