| Abstract: | One of the important influencing factors of the model of rock mass destruction is the constitutive model of the rock. Duncan-Zhang model is the most widely used non-linear elastic soil constitutive model in the geotechnical engineering. In this paper, the influencing factors of Duncan-Zhang nonlinear elastic model are analyzed and demonstrated with examples. The values determined and the match of some parameters in the constitutive model have a great impact on the application of the models and engineering calculations. |
