ABSTRACT
Based on our Part 1 article addressing lab test analysis, development and validation of the constitutive model EXPO-COM from TUC (Chair of Geomechanics and Multiphysics Systems of the Clausthal University of Technology), the practical application of the newly developed approach for the physical and numerical modeling of the crushed salt compaction is demonstrated in Part 2. The focus of the numerical investigation is to verify and demonstrate the following main capabilities of the numerical modeling equipment: functionality, numerical stability and plausibility of the delivered results. The demonstration is based on different functional numerical models (FM) with stylized illustration of the underground cavities filled with crushed salt for two different applications: (a) repository research (single drift with a representative geometry) to demonstrate the features of the constitutive model under different boundary conditions and (b) existing mines (single 3D-chamber characterized by a complex chamber geometry and complex 3D-mine-field) to demonstrate the functionality of the numerical equipment.
