Explanation of how the FEP is treated

Excavation/operation: 3DEC modelling of near-field effects of excavation of tunnels and deposition holes. Temperate: 3DEC modelling of thermal stresses and deformations in the near field and in the far field. Periglacial: 3DEC modelling of horizontal stress reduction caused by cooling. Glacial: 3DEC stress modelling of near field. ABAQUS modelling of far field. Earthquakes: Included in the modelling of shear movements.
