The fatigue test system is the main equipment to test the fatigue load performance of anchorage, but for a long time, due to the lack of calibration basis and the lack of effective traceability way, it is unable to calibrate the equipment. This paper analyzes the structure and working principle of the fatigue test system, and determines its measurement technical indicators and requirements through investigation and test verification. The calibration method of static force value is studied and verified by experiments. The uncertainty of static force calibration results is evaluated, and the static force calibration technology of fatigue test system with uncertainty better than 0.50% is formed, which lays a good foundation for the calibration of this kind of equipment.
