道路桥梁斜缝减缓跳车现象的理论分析

Theoretical Analysis on Phenomenon of Road and Bridge Inclined Cracks can Reduce Vehicle Jumping

对车辆经过道路桥梁横缝及斜缝的振动特性进行分析,结果表明,道路及桥梁中的接缝若与其横断面方向成一定的角度、避免横缝,则可以缓解跳车现象,同时对斜缝角度的大小进行了分析。

Vibration characteristics of the road and bridge cross joints and inclined cracks when vehicles passing by is analyzed and the result shows that if the joints of roads and bridges can form a certain angle with the cross section to avoid cross joints and then the vehicle jumping phenomenon can be effectively reduced. An analysis is also made on the inclined cracks angle.
