高速公路桥头跳车的理论与施工探讨

Study on the Theory and Construction of Bridgehead Jumping at Freeway

公路在我国交通事业的发展中发挥着非常重要的作用,近年来,桥头跳车成为公路施工建设中的突出问题。桥头跳车对行车的安全性、稳定性、舒适性等有非常明显的影响,严重的话会造成汽车的损害以及行车的安全。在桥头跳车的影响下,汽车容易产生颠簸,加重了对路面的荷载,在长时间的冲击作用下,路面往往在早期就出现损坏,不仅加重了汽车的养护费用,还缩短了公路的使用寿命。因此,分析和讨论桥头跳车的问题,提出有针对性的防治措施对公路建设意义重大。

Highway plays an important role in the development of China＇s transportation industry. In recent years, bridgehead jumping has become a prominent issue in the construction of highways. Bridgehead jumping has a very significant impact on the safety, stability and comfort of the traffic. If it is serious, it will cause damage to the vehicle and safety of driving. Under the influence of a bridgehead jumping,the car is prone to bumps and aggravates the load on the road surface. Under long-term impact, the road surface is often damaged at anearly stage, which not only increases the cost of car maintenance, but also shortens the service life of highways. Therefore, analyzing and discussing the problem of bridgehead jumping and proposing targeted prevention and control measures are of great significance to the construction of highway.
