Group 1 - The Liu Wudian Navigation Bridge has a total length of 1,948 meters, with a main span of 928 meters and a main tower height of 178.1 meters. The main tower consists of 60 steel shell segments and 2 steel cross beams, overcoming various technical challenges related to offshore construction and temperature control of large concrete volumes [3]. - The project team achieved a single segment axis deviation within 4 millimeters, with an overall deviation of approximately 9 millimeters, demonstrating true millimeter-level control through digital management and precision instruments [5]. - The offshore main line of the Xiamen section of the Xiamen-Jinmen Bridge is expected to be ready for traffic by the end of next year [5].
