| Abstract: | Taking the test of suspender cable force of a long span arch bridge as an example, this paper introduces the test methods of suspender cable force, and on the basis of measuring cable force with frequency method, a unified correction value of the calculated length of a suspender is used to correct the measured cable force. The results show that: this method is simple and reliable, and can be used for reference for the cable force measurement of similar arch bridges. |
