在现如今的路桥施工过程中,桥头跳车问题是一直困扰的问题之一。随着我国公路工程发展的逐渐加快,桥头跳车现象尤为常见。不仅对车辆通行的速度造成影响,而且还对车辆通行的舒适及安全造成影响。严重情况下会有安全事故发生。其次,当车辆在高速行驶的过程中出现跳动和冲击,不仅对路面及桥梁造成冲击荷载的加大,促使桥台、桥头路面及桥梁的伸缩装置造成破坏,而且在一定程度上还对车辆造成损坏。导致道路的使用寿命及社会效益受到影响。本文主要从公路桥头跳车现象出现的原因及整治措施进行详细的阐述。
In today’s road and bridge construction process, the bridgehead jumping problem has been one of the problems plaguing. With the gradual acceleration of the development of highway engineering in our country, the phenomenon of bridge jumping is particularly common. This not only affects the speed of the vehicle, but also affects the comfort and safety of the vehicle. In severe cases there will be a security incident. Secondly, when vehicles run at high speed, there is beating and impact which not only causes the impact loads on the pavement and bridge to increase, but also causes damage to the abutment, bridgehead pavement and the expansion and contraction devices of the bridge, and to some extent also causes the vehicle damage. As a result, the service life of roads and social benefits are affected. This paper mainly elaborates the causes of emergence of the phenomenon of vehicle jumping at highway bridgeheads and the remedial measures.
