设置预抛高法维修桥头跳车的机理及施工工艺
he mechanism and Construction Technology of the repair the Vehicle dumping by flip-height
路堤与桥台衔接处结构的不均匀沉降，产生了桥头跳车，影响行车舒适性, 加剧车辆的损坏, 严重时会导致交通安全问题，同时极大的增加了公路养护费用。在公路建设和使用期内加罩调坡时, 对桥头路段纵横坡进行预抛高处理, 可有效地抵消部分预期要产生的不均匀沉降,延缓桥头跳车现象的出现, 减少桥头引道的养护维修工作量。笔者从设置预抛高的机理出发，分析了该高速公路动态沉降监测情况，在这基础上，设置了预抛高，研究了配套的施工工艺。
he differential settlement of the structure convergence Department between Embankment with the abutment, resulting in the Vehicle dumpping,which it impact of road comfort, increased damage to vehicles, will lead to serious safety problems ,at the same time which it will greatly increase the cost of road maintenance. Set flip-height in the bridge head Along with the construction and repair of highway, which it will reduce the the differential settlement, delaye the Vehicle dumping,and reduce the workload of the bridge\
