BARIK
Development and testing of an extended Hoek-Brown material model to account for anisotropic strength behavior in the application of integrity criteria for crystalline host rocks
The research project BARIK aims to develop and test an extended three-dimensional Hoek-Brown material model capable of considering anisotropic strength behavior, specifically in a rock mass intersected by multiple fractures. The goal is to formulate the boundary condition in a way that adequately accounts for the strength-reducing properties of the respective fracture system during the integrity assessment. The new material model (BARIK material model) will be implemented and tested in two different computer codes. The use of two computer codes allows for the identification and evaluation of inaccuracies arising from the use of different codes. Using the BARIK material model, it will be examined whether the current formulation and quantification of the dilatancy criterion for crystalline host rocks is sufficient, or whether changes or specifications regarding the consideration of anisotropic strength behavior need to be made. In calculating the effective stress state, the Biot coefficient will also be used as a hydro-mechanical coupling parameter in the fractured rock. The project will be carried out in close collaboration with the Technical University of Bergakademie Freiberg.
