Compressed air energy storage (CAES) plants require periodic air injection and extraction based on energy demand. During the injection process, as compressed air is continuously injected, the mechanical energy of the compressed air is stored in the salt cavern. The storage capacity is largely determined by the size of the salt cavern and the maximum allowable pressure. During energy demand periods, the stored mechanical energy is converted back to electrical energy. As the compressed air decreases, the internal air pressure of the salt cavern will gradually decrease to the minimum operating pressure. Therefore, during the operation of the power plant, due to different operating schemes, the surrounding rock of the storage cavern will be subjected to cyclic loading, resulting in creep deformation and fatigue effects. Consequently, a comprehensive understanding and investigation of the creep and fatigue characteristics of rock salt are crucial for ensuring the safe operation of CAES salt cavern storage facilities.
