随着高速公路的迅速发展,在公路建设中,桥头跳车现象已成为高速公路的多发常见病害,严重影响行车的平稳性和安全性,桥头跳车问题已成为高等级公路的工程质量和造价的重要影响因素。桥头跳车的危害非常大,主要表现为:影响行车安全、降低行车速度、影响车辆运营费用和加速桥梁及路面的病害,对道路桥梁的运行影响极大。一些常规措施,尽管起到了一定的作用,但并非解决问题的根本出路。故此,在这里对这个进行一个比较系统的分析。 With the rapid development of expressway, in the highway construction, the phenomenon of bridge jumping at the bridgehead has become a common disease of expressways, seriously affecting the stability and safety of driving. The bridgehead jumping problem has become the project quality and cost of high-grade highways The important influence factor. The hazards of bridgehead jumping are very large, mainly as follows: affecting traffic safety, lowering driving speed, affecting vehicle operating costs and accelerating the diseases of bridges and pavements, which have a great impact on the operation of roads and bridges. Some conventional measures, although playing a certain role, are not the fundamental solution to the problem. Therefore, here for a more systematic analysis of this.
