Abstract
Different lab tests concerning creep behaviour and short term strength properties of bedded rock salt samples from Jintan, P.R. China have been performed by Sichuan University (SCU), the Chair in Waste Disposal and Geomechanics of Clausthal University of Technology (TUC) and the Institute for Geomechanics, Leipzig (IfG).
This paper presents the parameter determination for the constitutive model Lubby2 and the strength model Hou based on the above-mentioned lab tests. In this context the difficulties over the stress distribution within the salt samples are discussed. These difficulties result from deformation of the salt samples during the lab tests. Additionally a verification analysis of the determined parameters is presented, comparing measured lab tests data and calculated results with constitutive model Lubby2 and strength model Hou using the determined material parameters.
Last but not least some mechanical differences between bedded rock salt of Jintan, P.R. China and German high-purity rock salt are discussed. Jintan rock salt shows a relatively high content of clay minerals, however its mechanical behaviour is little different from the German rock salt.
