TL;DR: In this paper, an elasto-viscoplastic-creep model is employed to predict the stress-strain relation around the cavern during the construction and cyclic operation phases.

TL;DR: In this article, a robust and reliable metamodel for mechanized tunnel simulation in computationally expensive applications is proposed, which can reliably replace the finite element simulation model and drastically reduce the expensive computation time of the back analysis subroutine.

TL;DR: In this paper, a two-step simulation to analyze the thermo-mechanical behavior of rock salt in the vicinity of compressed air energy storage (CAES) caverns is presented, where changes in air temperature and pressure resulted from injection and withdrawal processes are estimated using an analytical thermodynamic model.

TL;DR: A time dependent model is selected to describe the mechanical response of the rock salt around the cavern, implemented in a finite element code and its application in numerical modeling of salt caverns is illustrated.

TL;DR: In this paper, an elasto-viscoplastic creep constitutive model is implemented into a numerical model of rock salt caverns to assess its behavior under different operation conditions, and sensitivity measures of different variables involved in the mechanical response of cavern are computed by elementary effect global sensitivity method.
