Uniaxial compression creep tests have been performed on a kind of rock salt similar material and laminated salt rock similar material on the base of salt rock gas-storage in Jintan. The creep tests show that the rheological property of the similar material is basically the same with the original rock. Under the uniaxial compression, the deformation gradually approaches to be constant after the early short stage of creep attenuation. The similar material shows stress-dependent behavior obviously under different stress stage, the greater the load the higher the creep ratio and creep deformation. A creep constitutive equation which is suitable to rock salt is used to the similar material, and it fits with the obtained creep data very well. The results show that the similar material developed in this passage has the same creep property as the original salt rock,and this material can be used to simulated the deformation and failure of underground gas storage constructed in bedded salt deposits.

The mechanical characteristics of rock salt have an important influence on the safety of the salt cavity. The acoustic emission (AE) technique was used to analyze the generation of microcracks in rock salt under uniaxial compression condition. By monitoring acoustic emission in whole process of stress - strain curve under uniaxial compression test, the damage characteristic of rock salt is obtained. The AE rate-strain curve is able to reflect the damage development process with better consistency evident with the cracks generating. The failure form of rock salt is mainly the shear failure under condition of low loading strain rate. After shear failure, a lot of small crushed particles spread on the surface of the failure surface. A damage constitutive model of rock salt is determined on the basis of acoustic emission characteristics, which could reflect the strength and deformation characteristics before the peak strength.
