我国高速铁路大量采用常用跨度预应力混凝土箱梁,部分运营高速铁路桥梁支座存在安装错误的情况,桥梁结构不能按设计规定方向变形伸缩,对线路平顺性产生了一定影响,给高铁运营安全带来了安全隐患。结合沪宁城际唐家村大桥、杭甬高铁柯桥特大桥支座更换整治的实例,研究解决运营高速铁路桥梁支座更换整治方法和措施,为高速速铁路无砟轨道桥梁支座更换整治积累资料和经验。
China’s high-speed railways use a large number of commonly-used prestressed concrete box girders, and some of the high-speed railway bridge supports are installed incorrectly. The bridge structure can not be deformed and retracted according to the design direction, which has a certain influence on the ride comfort of the high-speed railways. Came a security risk. Combining the Shanghai-Nanjing Intercity Tangjiacun Bridge, Hangzhou-Ningbo high-speed railway Keqiao bridge replacement replacement cases to study and solve the operation of high-speed railway bridge bearing replacement remediation methods and measures for high-speed railway ballastless track bridge bearing replacement accumulated Data and experience.
