Cable force adjustment of cable-stayed bridge has been a hotspot. The structure of the cable-stayed bridge is more complicated, and its cable force adjustment method is also difficult. In order to explore the reasonable method to adjust the cable force of the torsion cable-stayed Bridges, this paper discusses the objectives and principles of cable tension adjustment. The influence matrix method and the finite element analysis software midas civil 2012 of bridge structure are used to design the scheme. The cable adjustment scheme is developed by using the trial algorithm, and the cable adjustment effect is analyzed. Firstly, influence matrix method was used to analyze the mutual influence degree between adjacent cables. Then the adjusting value of cable force is calculated by iteration until convergence. Input the adjustment values of each step into the finite element analysis software to analyze the adjustment process and results The whole bridge is monitored and measured in the course of cable adjustment. The monitoring results show that the cable force is close to the target value after the adjustment of the cable force. The alignment of bridge deck after adjustment is also in good agreement with the design, and the deflection of tower top is improved. This practice will provide a more important reference for similar project.
