A creep reaction frame, a test specimen deformation jacket, a data acquisition system, and a triaxial chamber were readied and verified for their suitability for conducting triaxial creep tests of hard rock. All the equipment was found to be adequate for doing triaxial creep tests. A limited number of creep tests was conducted on anhydrite rock core from the Waste Isolation Pilot Plant WIPP site. Three of the four creep stages were observed during the testing. A logarithmic function was found to best fit the transient and steady-state creep stages.
