Abstract:A kind of construction technology of measurement and control of tied arch bridge based on intelligent tensioning devices was mainly introduced, which can test the force under anchor plate effectively without the effect of stiffness and boundary conditions. While the construction quality of the cable was controlled and the bridge quality was improved. The construction technique has been applied in the construction of a through tied arch bridge in China and has achieved good results.

Keywords:intelligent tensioning; frequency method; measurement and control; construction technology
