Influence of the Variability of Compressed Air Temperature on Selected Parameters of the Deformation-Stress State of the Rock Mass Around a CAES Salt Cavern

The article presents the results of a numerical simulation deformation-stress state in rock mass around salt cavern which is part CAES installation (Compressed Air Energy Storage). model based on parameters Huntorf power plant installation. influence temperature and salt-creep speed stability storage was determined basis three different stress criteria effort points at time intervals. analysis includes two creep speeds, represent types salt. solutions showed that importance when considering distance less than 60 m from axis (at diameter 30–35 m). With an increase diameter, it possible impact range will be proportionately larger, but each case requires individual modeling shape working cycle.
