高速公路桥头跳车防治关键技术研究

Research on Key Techniques for Preventing Car Jumping at Expressway Bridgehead

当前我国高速公路建设处于高速发展阶段,桥涵通道等构造物数量与日俱增。桥头跳车是一种常见病害类型,研究表明其不仅会降低行车的舒适性,还会加速桥台等构件的损坏速率。为此,必须了解高速公路桥头跳车危害,本文结合工程实际,通过规范施工工艺,提高施工技术水平等方法,以期解决桥头跳车问题,提高工程施工质量。

At present,China's expressway construction is in a high-speed development stage,and the number of bridges,culverts and other structures is increasing day by day.Bump at bridge head is a common type of disease,which will not only reduce the comfort of driving,but also accelerate the damage rate of components such as abutment.Therefore,it is necessary to understand the harm of vehicle jumping at the bridgehead of expressway,standardize the construction technology and improve the construction technology level in combination with the actual situation of the project,so as to solve the problem of vehicle jumping at the bridgehead and improve the construction quality of the project.
