| 摘 要： | 桥头跳车是高速公路开放通车后的质量通病之一。首先分析了产生桥头跳车的原因,然后对桥头搭板、土工格栅以及CFG桩复合地基3种治理桥头跳车的方法进行介绍和分析,确定了3种方法的适用范围。对软土地基上的桥头跳车问题可以通过采用CFG桩复合地基并配合设置桥头搭板或过渡板来解决。

| Abstract: | The bumping at the end of bridges is one of the quality common faults after the super level highways are open to traffic.The reasons for the bumping at the end of bridges were firstly analyzed in this paper.Then the treatment methods to bumping at the end of bridges with slabs at the end of bridges,geogrid and CFG pile composite foundation were introduced and analyzed.Their application scopes were determined.CFG pile composite foundation set with slabs at the end of bridges can be used to treat the bumping at the end of bridges on soft soil foundation. |
