某悬臂梁桥加固效果探析

Analysis on reinforcement effect of a cantilever girder bridge

采用荷载试验方法对某悬臂梁桥加固效果进行研究,结合桥梁加固前后静载试验和动载试验各测试指标的对比,综合评估其加固效果。得出此类加固方法能提升桥梁的强度及刚度,但会增大车辆对桥梁的冲击、降低行车舒适性。通过研究,为类似桥型加固方法提供一定的工程经验。

The reinforcement effect of a cantilever girder bridge is studied by using load test method,and the reinforcement effect is comprehensively evaluated by comparing the test indexes of static and dynamic load tests before and after the bridge reinforcement.It is concluded that this kind of reinforcement method can improve the strength and stiffness of the bridge,but will increase the impact of vehicles on the bridge and reduce the driving comfort.Through the research,some engineering experience is provided for similar bridge reinforcement methods.
