“…The phenomenological analysis method, the viscoelastic plasticity model, and the empirical formula are the main methods used for constructing the rock salt constitutive relation (Munson et al, 1993). In this study, the foundational model was defined by the classical creep constitutive model obtained by the empirical formula method.…”

“…t creep < 0). This phenomenon is observed in the laboratory during uniaxial multi-step creep tests and is referred to as "inverse creep" (Van Sambeek, 1993;Hunsche, 1991;Munson et al, 1996;Charpentier et al, 1999). The effects of transient inverse creep in a cavern have been described by Hugout (1988) In this paragraph, the origin of time is the day when cavern leaching is completed.…”

Résumé -Essais d'étanchéité dans les puits d'accès aux cavernes dans le sel -Des milliers de cavernes ont été creusées par dissolution dans des formations salifères ; elles sont utilisées pour stocker une grande variété de produits fluides, depuis l'air comprimé et l'hydrogène, jusqu'aux GPL, au gaz naturel et au pétrole brut. Ces cavernes doivent être étanches. Cet article présente les différents facteurs qui contribuent à la formation des fuites et à leur prévention : la distribution des pressions de fluide, l'environnement géologique, la qualité de la cimentation, l'architecture du puits. L'accident de Mont Belvieu est rappelé : il met en évidence l'importance des essais périodiques d'étanchéité. Nous présentons également les divers essais possibles, et nous distinguons les notions de fuite apparente, de fuite corrigée et de fuite réelle. Les facteurs contribuant à la fuite apparente sont examinés. Deux essais réels in situ sont décrits, utilisant respectivement du fioul et de l'azote comme fluide d'essai ; nous montrons qu'une analyse précise des résultats de l'essai permet d'évaluer correctement la fuite réelle en la distinguant des autres facteurs avec lesquels elle pourrait être confondue.Mots-clés : cavernes dans le sel, étanchéité des puits, essais d'étanchéité, vérification de l'intégrité mécanique. fuel-oil density, kg/m 3 Σ annular space cross-section area, m 2 θ o brine temperature at the end of leaching, °C θ R rock temperature at cavern depth, °C χ ratio between gas density and gas pressure, kg/m 3 /Pa.

“…is process may be individually controlled by one mechanism under some specific conditions; however, it is controlled by several mechanisms in parallel in the vast majority of cases. Munson et al [83] summarised the microcreep deformation mechanisms of salt rock under different conditions. e results showed that the creep deformation of salt rock is mainly controlled by the dislocation slip mechanism under high-stress conditions, while it is controlled by dislocation climb mechanism under low stress and high temperature conditions.…”

Due to the advantages of low porosity, low permeability, high ductility, and excellent capacities for creep and damage self-healing, salt rock is internationally considered as the ideal medium for underground storage of energy and disposal of radioactive waste. As one of the most important mechanical properties of salt rock, creep properties are closely related to the long-term operation stability and safety of salt rock underground storage cavern. A comprehensive review on the creep properties and constitutive model of salt rock is put forward in this paper. The opinions and suggestions on the research priority and direction of salt rock's mechanical properties in the future are put forward: (1) permeability variation of salt rock under the coupling effect of temperature and stress; (2) damage mechanism and evolution process under the effect of creep-fatigue interaction and low frequency cyclic loading; (3) microdeformation mechanisms of salt rock and the relationship between microstructure variations and macrocreep behavior during creep process; (4) the establishment of the creep damage constitutive model with simple form, less parameters, easy application, and considering the damage self-healing ability of salt rock simultaneously.
