In this paper, basing on the results of soil tests, introducing the concept of damage, considering soil's structure, the author modify the Duncan - Changmodel.
本文结合室内试验结果，引入损伤的概念，考虑土的结构性，对邓肯—张模型进行了修正。

The model parameters can be converted from the parameters of the Duncan-Changmodel.
模型参数可由邓肯-张模型参数换算。

The elasticity modulus in Mohr-Coulomb model was modified by employing the processing method of tangential modulus in Duncan-Chang nonlinear model.
