Research of influence factors and countermeasures of lateral crawling of curved beam bridges
With the development of urban transportation,curved beam bridges have become the preferred bridge type for interconnecting different roads.The unique stress characteristics of curved beam bridges can easily cause lateral crawling diseases,such as bearing detachment,expansion joint damage and pier column cracking.On the basis of summarizing and analyzing the crawling diseases and their causes,the influencing reasons and degrees of different factors from both active and passive perspectives were analyzed.And the corresponding prevention and reinforcement measures for the new bridges design and the reinforcement design of operational bridges and were proposed.The research results of this article can pro-vide certain guidance for the new design and reinforcement countermeasures of curved beam bridges in the future.
