Density is the essential factor to decide the initial elastic modulus, and the elastic modulusinshear process is the result of combined action of stress status and density.
密度是决定初始弹性模量的根本因素，而剪切变形过程中弹性模量则是密度和应力状态共同决定的。

Elastic shear strain inshear band was dependent on shear elastic modulus, damage variable and residual shear modulus.
考虑刚度劣化后，剪切带的弹性应变由弹性剪切模量、损伤变量及残余剪切模量确定。

In thiS model, non-uniformly variations of soil density and shearmodulus with depth are taken into consideration. Numerical computations are conducted for typical cases.
