| Abstract: |
For novel arch rib, it is difficult to control the accuracy of the segments and whole bridge, especially for special shape bridge. It is also hard to balance the maximum lateral displacement (MLD) of arch rib and the maximum axis force (MAF) of jigs when removing temporary supports at high altitude. To address these issues, firstly, the derrick arch bridge with a total span of 231 meters is taken as the research object. Following the establishment of the finite element (FE) model of the bridge, an innovative criterion is proposed to consider both axis position and inclination angle, in which the error during the closure stage of the bridge is controlled availably. Secondly, among three potential plans modeled with FE model, one was chosen to remove the jigs, which effectively reducing the MAF and the MLD. Finally, the field monitor tests were proofread with FE model results to ensure the reasonable state of the bridge. |
