| Abstract: | Bailu bridge of Jingdezhen City and Longcheng bridge of Changzhou City are taken as examples to introduce the key construction technology for uplifting of main bridge tower in details, namely construction method of ＂horizontal assembly and integral vertical rotation＂ is adopted to realize positioning of main tower through vertical rotation. Basic theory and method of virtual prototype technology are applied in the analysis on bridge construction technology. Load duration during uplifting of main bridge tower and load bearing conditions at several key positions during construction of main tower are obtained through model establishment and simulation. Construction plans are optimized, design efficiency is improved, and construction quality and safety are guaranteed. |
