1. The Bentonite Barrier - Swelling Properties, Redox Chemistry and Mineral Evolution
Sammanfattning : Bentonite is planned for use as a buffer material in high-level radioactive waste repositories, where safety assessment is performed for very long periods (100-1000 ka). This thesis focuses on the swelling of smectites in liquid water, and analysis of bentonite from field experiments at Äspö Hard Rock Laboratory, Sweden. LÄS MER
2. Rock Mass Response to Coupled Mechanical Thermal Loading : Äspö Pillar Stability Experiment, Sweden
Sammanfattning : The geological disposal of nuclear waste, in underground openings and the long-term performance of these openings demand a detailed understanding of fundamental rock mechanics. A full scale field experiment: Äspö Pillar Stability Experiment was conducted at a depth of 450 m in sparsely fractured granitic rock to examine the rock mass response between two deposition holes.

3. Inversion and interpretation of hydraulic and overcoring stress measurements in the Äspö region, Sweden
Sammanfattning : .... LÄS MER
4. Structural and neural network analyses of fracture systems at the Äspö Hard Rock Laboratory, SE Sweden
Sammanfattning : 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. LÄS MER
5. New developments of the Integrated Stress Determination Method and application to the Äspö Hrad Rock Laboratory, Sweden
Sammanfattning : 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. LÄS MER
