桥头跳车是道路工程中常见病害,在软土地基条件下设计等级不高的国省道尤为严重。传统的“逐年加铺”或“开膛破肚”的维修方式难以满足运营条件下国省道“快速、经济、可靠”的养护要求。本工法处理桥头跳车,施工简便、早期强度高,开放交通早,施工工期短优点,是处理桥头跳车有效手段,值得推扩。 Bridgehead jumping is a common disease in road engineering. It is especially serious when the design level is not high in the soft ground. Traditional maintenance methods such as “increasing year by year” or “unwinding” can hardly meet the maintenance requirements of “fast, economical and reliable” under the conditions of operation. This method of handling the bridge at the end of the trip, construction is simple, early high strength, open traffic early, short construction period is an effective means of dealing with the bridgehead jumping is worth pushing.
