Abstract
Since several years, the demand for the storage of gas in rock salt caverns has changed from seasonal to high cycling operation. The new operation mode requires relatively fast pressure change rates in the cavern which in turn leads to temperature changes in the gas. The consequences of these temperature changes on the stressing of the rock salt mass cannot be neglected any more. For this reason, gas storage caverns require a more detailed rock mechanical consideration of thermal induced stresses in the salt rock mass. In the proposed paper the rock mechanical design with respect to the stress state in the vicinity of gas storage in salt caverns under consideration of thermo-mechanical coupled calculations will be presented. Numerical models are created to take into account the essential influence of the volume and depth of the cavern. Furthermore time-dependent, thermo-mechanical coupled numerical calculations are carried out. The influences of different model variations are going to be analyzed regarding the stress state surrounding the storage cavern.
