The Design of Anti-collision Guardrail Maintenance and Reconstruction Treatment Scheme for Baicaokou No.2 Bridge

以G55高速公路忻州段白草口2号大桥防撞护栏维修改造处治工程为实例,根据《公路交通安全设施设计规范》(JTG D81—2006),对预埋钢筋的锚固长度进行计算,提出了桥梁防撞护栏维修改造处治的设计方案。

Taking the anti-collision guardrail maintenance and reconstruction treatment engineering of No.2 bridge of Baicaokou in G55 Highway Xinzhou section as an example, according to the ＂Design Specification of Highway Traffic Safety Facilities＂, this paper calculated the anchorage length of the embedded reinforcement and put forward the design scheme of bridge anti-collision guardrail maintenance and reconstruction treatment.
