“…Some models describe the transient and stationary state of the strain (Lux et al, 2001), while others are quite complex and are therefore difficult to use. The models based on the strain microphysic approach seem to describe correctly the rock salt behaviour, but their prediction capacity is not completely definitive (Munson and Dawson, 1984;Poirier, 1985;Spiers and al., 1990;Aubertin et al, 1991aAubertin et al, , 1991bAubertin et al, , 1991cAubertin et al, , 1996Munson et al, 1996). However, there is not a unanimous view regarding the presence or the absence of a stationary phase and the latter remains subjective to the in-situ data measures analysis.…”

The work presented in this paper comes as part of a research program dealing with the thermomechanical behaviour of rock salt. It aims to study laboratory and in-situ long-term behaviour by means of creep tests with deviator and temperature changes. The laboratory results, using a triaxial multi-stages creep tests, highlighted the strain hardening character of rock salt. Furthermore, the in-situ results, using a borehole dilatometer multi-step creep test, have shown that the drilling is carried out in a weakly stressed pillar. The interpretation of the laboratory results, using the J.LEMAITRE law, did not indicate full agreement with all the test results. As a result a 'double' J.LEMAITRE model, which takes into account a double strain hardening variable, has been put forward. The validation of this model on the laboratory creep tests is very satisfactory. Furthermore, the activation energy seems satisfactory to represent the influence of the temperature. The in-situ behaviour modelling is clearly more complex than the modelization based on laboratory tests. In fact, it seems that if the rock salt behaviour is maintained by J.LEMAITRE law, it is necessary to vary with the stress, at least, one of the parameters assumed constant in the basic law.

“…These lows have been applied to correlate the straintime curve in different temperature and stress by taking into account creep mechanism map. Over the years, in 1990's decade, more phenomena such as dilatancy and healing were included by developing new lows, for instance in SUVIC (Aubertin et al, 1991), Cristescu (Cristescu, 1993), or Günther-Salzer (Günther et al, 2010). In last years, in third step, early models were improved to take into account more phenomena as well: A version of Munson-Dawson (Munson, 1993) included inverse creep, and both the MDCF model evolving from Munson-Dawson and Lux-Wolters (Wolters et al, 2012) evolving from Lubby2 now include dilatancy, healing Table 2.…”

Salt rock has been used as hast rock to storing hydrocarbons and disposing nuclear wastes because of its low permeability. On other hand it deforms under even low deviatoric stress which threatens the structural stability of salt caverns. Rock mechanical stability is one of important stages in salt cavern's design and construction, though mechanical factors (such as nonlinear behavior of rock salt), thermal factors (such as temperature changes during injection and production) and hydraulic factors (such as salt permeability and viscosity of stored material) affect on short term and long term behavior of salt cavern. Various criteria and methods have been investigated for salt cavern's design and stability analysis. In this paper, by taking into account the importance of structural stability of salt cavern, the general behavior of rock salt and salt cavern are given. It reviews the various design concepts and methods and, in the following, stability criteria including stress-based and damage-based are also discussed. It is assigned that the RD stability criterion is more comprehensive than others.

“…Those could range from models like the Unified Creep-Plasticity model (Aubertin et al 1991) to the Multi-mechanism Deformation (Munson, et al 1989) and the Multi-mechanism Deformation Coupled Fracture (MDCF) (Chan et al 1999) models of Munson and co-workers. The latter two models have been extensively used at the Waste Isolation Pilot Plant (WIPP) for years because they can model a wider range of rock salt behavior (including primary, secondary, and tertiary creep, for the case of the MDCF model).…”

This report describes the progress in fiscal year 2010 in developing the Waste Integrated Performance and Safety Codes (IPSC) in support of the U.S. Department of Energy (DOE) Office of Nuclear Energy Advanced Modeling and Simulation (NEAMS) Campaign. The goal of the Waste IPSC is to develop an integrated suite of computational modeling and simulation capabilities to quantitatively assess the long-term performance of waste forms in the engineered and geologic environments of a radioactive waste storage or disposal system. The Waste IPSC will provide this simulation capability (1) for a range of disposal concepts, waste form types, engineered repository designs, and geologic settings, (2) for a range of time scales and distances, (3) with appropriate consideration of the inherent uncertainties, and (4) in accordance with robust verification, validation, and software quality requirements.Waste IPSC activities in fiscal year 2010 focused on specifying a challenge problem to demonstrate proof of concept, developing a verification and validation plan, and performing an initial gap analyses to identify candidate codes and tools to support the development and integration of the Waste IPSC. The current Waste IPSC strategy is to acquire and integrate the necessary Waste IPSC capabilities wherever feasible, and develop only those capabilities that cannot be acquired or suitably integrated, verified, or validated. This year-end progress report documents the FY10 status of acquisition, development, and integration of thermal-hydrologicchemical-mechanical (THCM) code capabilities, frameworks, and enabling tools and infrastructure.iv ACKNOWLEDGEMENTS
