英文摘要	Salt caverns are utilized widely as natural gas storage and compressed air energy storage because of rheology and low-permeability of salt. For both natural gas storage or energy storage, gas injection and gas withdrawal are carried on alternately, two cycles one year for natural gas storage while one cycle every day for compressed air energy storage. For investigation of mechanical characteristics of rock salt under injection and withdrawal cycles, triaxial cyclic loading tests were conducted using a MTS test system. Linear relationships between stress and strain under unloading and reloading were observed. The linear character of the stress-strain response during reloading and unloading is more apparent at an increased confining pressure. Confining pressure reduces the difference of deformation modulus between unloading and reloading. The constitutive relationship for loading and unloading was constructed and proved by fatigue testes.
