桥头跳车现象是指车辆在行驶过程中发生明显的颠簸现象,桥头跳车不仅直接影响车辆的行驶速度,严重时会造成交通事故。当车辆产生桥头跳车现象时,也会加速桥头、桥台路面及桥梁伸缩装置的损坏。本文简要对桥头跳车产生的原因进行了分析。通过分析软基路堤桥头跳车的原因,提出在实际工程中用气泡混合轻质填土技术解决桥涵跳车问题的具体措施。
The phenomenon of bridgehead jumping refers to the obvious bumpy phenomenon of the vehicle during its driving. The bridgehead jumping not only directly affects the traveling speed of the vehicle, but also causes serious traffic accidents. When the vehicle produces the phenomenon of jumping at the bridgehead, it will speed up the bridgehead, abutment pavement and bridge expansion device damage. This article briefly analyzes the causes of bridgehead jumping. Based on the analysis of the reasons for the jumping at the bridge head of soft foundation embankment, this paper puts forward the concrete measures to solve the problem of bridge and culvert jumping by using the technology of bubble mixing light filling in practical engineering.
