摘　　要：分析认为结构突变、地基沉陷、填土压缩沉降、施工管理存在缺陷是造成桥头跳车病害的主要原因,并提出了对应的处理措施,包括处理台后软弱地基、严格控制台背填料的选择及施工质量、对桥头处路面进行处理以及合理安排施工。Through analysis, the paper figures that the main causes inducing vehicle bumping at bridge head are structure break, foundation siking, settlement of compressed filling, and the defect of construc- tion management. Furthermore, the paper proposes the corresponding measures such as dealing with the soft foundation of abutment backwall, strictly controlling the selection of abutment backwall filling and the construction quality, disposing the pavement at bridge head and arranging the construction rationally.
