The tensile creep test of the post-installed anchor was carried out by the improved spring type creep test equipment. The measurement of creep deformation from non-load and creep fracture time was possible over a long period of time by this equipment. The creep deformation at about 1/3 load of the maximum load increase slightly for the duration of 90 day, but the creep deformation is very small, and creep fracture will not occur in 50 years. And at 80% of the maximum load, creep fracture occurred in 168 days.
