摘要：

The constitutive model TUBSsalt takes into account multiple phases of deformation. The model consitst of additive terms representing the elastic behavior, the three creep phases primary, secondary and tertiary creep as well as failure by shear or tension. TUBSsalt is also able to calculate recovery creep and healing of rock salt. In order to determine the parameters needed by the constitutive model, a set of laboratory tests has to be analyzed. These tests contain multi-phase creep tests, triaxial strength tests and healing tests, which are used to get a unique set of parameters for a specific type of rock salt. All these tests can be simulated by the constitutive model TUBSsalt.
