    Abstract : The > 10,000 fractures documented in the 450m deep Äspö Hard Rock Laboratory (HRL) provide a unique opportunity to study brittle deformation of a Swedish bedrock mass. The fracture population consists of six major sets, one subhorizontal and five sub-vertical. READ MORE

  3. 3. New developments of the Integrated Stress Determination Method and application to the Äspö Hrad Rock Laboratory, Sweden

    Author : Daniel Ask; KTH; []
    Keywords : Integration; Rock Stress; ISDM; Äspö HRL;

    Abstract : This thesis presents new developments of the IntegratedStress Determination Method (ISDM) with application to the AspoHard Rock Laboratory (HRL), Oskarshamn, Sweden. The newdevelopments involve a 12-parameter representation of theregional stress field in the rock mass. READ MORE

  4. 4. Hydromechanical Behaviour of Fractures Close to Tunnels in Crystalline Rock

    Author : Johan Thörn; Chalmers University of Technology; []
    Keywords : Fracture stiffness; Fracture geometry; Laboratory experiments; Äspö HRL; Rock stress; In situ; Deformation measurement; Hallandsås; Hydromechanical coupling; Geological history;

    Abstract : The deformation and stiffness properties of rock fractures are important measurable parameters when describing their hydromechanical behaviour. Deformation refers to aperture change. Stiffness refers to the amount of deformation per stress change to which a fracture is subjected. READ MORE
