The presented method involves applying cylinder gradient abutment to control bridge level so that the uniform magnitude between bridge descending and roadbed sinking can be obtained,and road vertical curve is thus kept smooth and bridge jumping eliminated.
分析软土地基上路堤与桥梁的沉降差异及跳车的原因,采用桥随路降的治理方法,应用柱式升降桥墩来调控桥面高程,使桥面降落高度与路面沉降量一致,保持道路竖曲线顺畅,消除桥头跳车。
