Study on Identification and Monitoring of Long-Span Bridges in Service Based on GPS and BDS Dynamic Observation
As an important part of modern traffic construction and operation, the repair and maintenance of long-span bridges has received more and more attention by the industry. With the increasing span and width of long-span bridges, more attention should be paid to the durability and safety of long-span bridges compared with conventional bridges. In the present stage of long-span bridges, the accuracy of deformation identification and safety monitoring of long-span bridges cannot be ensured because of the small variation of creep deformation amplitude and the limitation of traditional conventional technology in positioning accuracy. Therefore, a continuous quasi-static model based on GPS and BDS observation data is proposed to identify and monitor long-span bridges. At the same time, specific experiments are carried out in combination with practical engineering cases. The results show that this method has strong effectiveness by providing some ideas and reference directions for traffic construction and operation, repair and maintenance of modern highway bridges.
