Abstract
The paper presents an updated hypoplastic constitutive model by introducing a new term. Moreover, an extension to include cohesion into the model is made. The model is implemented in a finite difference code. The procedure for parameter identification is presented. The numerical implementation is verified by some element tests. Finally, the constitutive model is used to simulate excavation and support of a shallow tunnel.
