Analysis on the Influence of Deformation and Settlement of Cable-stayed Bridge Support on the Structure
With the increasing operation mileage of domestic highways,the number of bridges is also increasing.Various unexpected incidents often occur,which puts forward higher requirements for the operation and management of bridges,especially for the management and maintenance of various bridges with special and complex structure.Aiming at the unexpected incident of abnormal height difference of the expansion joint device at the end of a cable-stayed bridge,in order to find out the cause of the incident and analyze its influence on the overall structure of the bridge,the bridge deck elevation,the expansion joint height difference,the main tower verticality,and the whole bridge's cable force are tested and analyzed,and the bridge is tested again after repair.Through the comparative analysis of the data before and after the repair,the objective and practical judgment is made,aiming to provide technical basis for the reopening of the bridge.
