1. Lined underground openings : rock mechanical effects of high internal pressure
Sammanfattning : .... LÄS MER
2. Thermo-Mechanical Behaviour of Refrigerated Caverns in Hard Rock
Sammanfattning : For almost 4 decades, underground caverns in hard rock have been used to store liquefied petroleum gases (LPG) and refrigerated products, such as foods and chemicals. The design of such facilities has, however, been founded on relatively limited knowledge of the reaction of rock masses to cooling. LÄS MER
3. Rock Mechanical Consequences of Refrigeration. A Study Based on a Pilot Scale Rock Cavern
Sammanfattning : The deformation of a rock mass due to temperature decrease below freezing is very complex, since many factors are involved; thermal strain, strain due to stress change, stress re-distribution, ice formation and the temperature dependency of rock mechanical and thermo-physical properties. The objective of this study was to achieve a better understanding of the rock mass response to thermo-mechanical loading when storing low temperature products in rock caverns excavated in hard crystalline rock masses.

4. Modeling aspects of reliability-based design of lined rock caverns
Sammanfattning : The storage of large quantities of hydrogen gas in underground lined rock caverns (LRCs) could contribute to an efficient supply of fossil-free energy. The consequences of failure of such storage can be catastrophic, so representative predictive models and a small probability of failure are needed for the LRC design. LÄS MER
5. Water Curtains in Gas Storage. An Experimental Study
Sammanfattning : Water curtains have been used for more than 20 years to prevent the escape of gas from caverns excavated in rock. Today, the use of water curtains appears to be increasing, with applications in various forms of storage caverns. LÄS MER
