| Abstract: | For in-depth study on the construction control method of large span cable-stayed bridge tower and girder,taking a project as an example,construction factors of tower and girder were analyzed,and the main influence factors were identified to formulate the corresponding control measures.The results show that the main influence factors of tower and girder construction include tower verticality,anchoring of the catheter,construction of the steel skeleton and the hanging basket,concrete pouring,the cable force and vertical control.According to the main influence factors,the measures and control points in construction were proposed and proved to meet the code requirements. |
