Abstract

In order to effectively correct the stay cable length error during the construction of the cable-stayed bridge, this paper proposed a correction method with the exposure of the sockets as the error control index and analyzed the influence of the elastic modulus, temperature effect, and anchor point coordinates of the cable on the cable length error from the perspective of construction control. Then, error correction was achieved by adjusting the position of the manufacturing cable length and the nut at the anchor end. The results of application in Jiayu Yangtze River Highway Bridge show that this method can improve the consistency between the actual amount of sockets and the theoretical value after the completion of cable tension, make the nut in the effective thread area of the sockets, and ensure the efficient implementation of the installation and tension of the cable during the cantilever erection of the main beam of the bridge.
