由于桥梁伸缩缝破损、老化而导致的跳车病害已严重制约高速公路的发展。车辆在桥梁伸缩缝处的跳车不仅降低了行车的安全、舒适性以及高速公路的总体质量,同时也缩短了运行车辆的使用寿命。分析了公路上常见的桥梁伸缩缝处跳车问题的成因,提出了桥梁伸缩缝处跳车的防治与维修措施。
Due to the broken bridge expansion joints, aging caused by the disease has seriously hampered the rapid development of the highway. The vehicle’s jerk at the bridge expansion joint not only reduces driving safety and comfort and the overall quality of the freeway but also shortens the useful life of the running vehicle. The causes of the problem of jerk at the bridge expansion joint, which is common on the highway, are analyzed. Preventive measures and maintenance measures are given for the jerk at the bridge expansion joints.
