桥梁吊杆受撞后检测方法及安全评价探讨

Discussions on Testing Methods and Safety Assessment of Bridge Booms after the Collision

文章以钢管拱桥六景特大桥吊杆被车辆撞击事故为工程实例,采用桥梁外观损伤检测、吊杆索力测试及荷载试验方法,评价被车撞后钢管拱桥梁的安全状况,为同类型被车撞后桥梁的安全性检测评定提供方法参考。

With the boom collision accident by the car of steel-pipe arch bridge Liujing Large Bridge as the engineering example,this article used the exterior bridge damage detection,boom cable-force test and load test methods to evaluate the safety state of steel-pipe arch bridge after the collision by a car,thereby providing the method reference for the safety detection assessment of the bridge after the car collision.
