扩容角越大,剪切带最终可以获得越来越高的剪切应变和体积应变.

Higher DA results in higher values of shear strain and volumetric strain in shear band.

较高的孔隙压力，即使试样的轴向应变为低，可以达到较高的横向变形和泊松比，以及负体积应变。

Higher lateral deformation and Poisson's ratio as well as negative volumetric strain can be reached for higher pore pressure even though axial strain of specimen is lower.

数值算例表明：（1）发生应变局部化时，塑性剪切应变和塑性体积应变主要集中在应变局部化带中；

The numerical examples indicate that: (1) when strain localization appears, the plastic shear strain and the plastic bulk strain mainly concentrate in localization band;

通过耦合应力的建立以及耦合应力与塑性体积应变一维化本构关系的推导，从全新的视角介绍了一种理解和建立土本构模型的方法。

From a new visual angle, a method for understanding and establishing the soil constitutive model is introduced by deducing the coupling stress and one-dimensional constitutive relation.
