摘　　要：桥梁在暴恐、战争、撞击、自然灾害突发下易遭受损坏,且不易修复,桥墩作为梁体的支撑结构,其出现损伤将会导致整座桥梁的通行中断,因此,开展紧急状态下的桥墩快速抢通与修复研究十分必要。首先归纳中国铁路与公路桥墩抢修器材发展现状,结合当前及未来发展需求分析其存在的不足,不足之处主要体现在使用种类单一、应用范围局限、拼架技术匮乏、结构形式单调、不具备“临-永”转换功能等方面,在此基础上提出解决思路及方法,可为提升桥墩应急保障能力提供技术支撑。Bridges are suscepible to damage by riot,war,impact,and natural disasters and are not easy to repair.The bridge pier,used as the supporting structure of the beam body,if damaged will cause the entire bridgeto be interrupted.Therefore,it is very necessary to carry out research on the rapid recovery and repair of bridgepiers under emergency conditions.This paper firstly presents an overview of the development status of emergencyrepair equipment for railway and highway bridge piers in China,and identifies their shortcomings in the view ofcurrent and future development needs.The main shortcomings include the single type of use,the limited application scope,the lack of assembling technology,the monotonous structural form,and the lack of"temporary-permanent"conversion function.Based on these facts,solutions and methods are put forward,which can providetechnical support for improving the emergency support capability of bridge piers.
