[0002] In modern bridge construction, single-column pier bridges can not only improve spatial layout and vision, but also beautify the appearance of the bridge. They have been widely used in projects such as highway interchange ramp bridges and urban overpasses. However, in recent years, with the continuous increase in traffic flow, the number of overloaded and heavy vehicles has increased, and speeding has occurred from time to time, resulting in beam torsion and deformation, uneven force on the supports and emptying of the single-column pier bridges during operation, endangering the safety of the bridge.
