Anti-overturning Performance Analysis and Reinforcement Evaluation of Single-column Pier Concrete Continuous Curved Box Girder Bridge
Based on the in-depth research on the instability and overturning mechanism of single-column pier concrete continuous curved box girder bridge,the corresponding numerical simulation method is used to construct the calculation model,and the influence of the new steel cover beam measures on the anti-overturning stability of the actual bridge is verified.The results show that the scheme conforms to the existing standard conditions,has rationality and practicability,and has certain reference significance for similar engineering.
