Abstract
Study on long-term stability of gas storage built in bedded rock salt is one of the most important contents of safety evaluation. This paper probes into long-term stability of gas storage built in bedded rock salt via the WIIPP model and proposes numerical solution of WIPP creep model. Conclusions can be drawn after creep numerical analysis on single storage cavern: (1) There exists differences between interlayer creep deformation and that of salt rock layer.(2)Size of internal pressure exerts important affect on convergent deformation of cavern. The lower the pressure, the larger convergent deformation of cavern is and ratio of convergence is nonlinear. And at early stage, bulk decreases evidently then gradually becomes steady
