The model in this paper has few parameters and can reflect the aspects of load transfer function, such as hardening, softening and affects of confiningstress.
模型具有参数较少且确定简单的特点，能反映荷载传递函数的性质，如硬化与软化，以及围压的影响。

Effect of initial mean effective stress on the behavior is examined by tests under undrained cyclic loading at several initial confining stresses with the same stress rations.
试验初步研究了通过用初始有效平均正应力归一化的有效应力路径，归一化有效应力路径有很好的一致性。

The plastic deformation of expansive clay can be reflected on the height, area and volume changes of soil body, but more significantly on height change due to the confiningstress.
