高速公路以其快捷、舒适、方便等优点在我国得到快速发展 ,但美中不足的是路桥过渡段的“跳车”现象频繁 ,影响行车速度和舒适感 ,给行车安全带来隐患。从设计及施工两方面论述了减少或消除高速公路路桥过渡段不均匀沉降的预防措施 ,结合某高速公路过渡段施工的过程 ,重点介绍了过渡段不均匀沉降的施工过程控制。

Because of its advantages the express highway developed fast in out country. But the frequent' bump' phenomenon in transition section influence the speed and comfort in driving and bring danger for driving safety. In this article for two aspects: design and construction the prevention measures are proposed to reduce or eliminate the different settlement in transition section. And combined with construction process of transition section the construction process control is mainly introduced.
