自1996年铁路提速以来,随着列车运行速度的不断提高,几大干线上桥梁的横向振动超限问题越来越突出,对铁路的安全运营构成了很大威胁,为确保列车的行车安全,桥梁设备管理单位急需对辖区桥梁振动情况进行经常性检测,以便能及时了解桥梁技术状态,防患于未然。因而对于进行桥梁检测、管理、维修养护的各单位来说,有一套能满足现场及时、便携、准确地了解桥梁振动情况的检测分析系统显得尤为重要。
Since the acceleration of the railway in 1996, with the continuous increase of the train running speed, the transverse vibration overrun problem of bridges on several main lines has become more and more prominent, posing a great threat to the safe operation of the railway. In order to ensure the train driving safety, Bridge equipment management unit urgently needs to carry on the regular inspection to the bridge vibration situation in the jurisdiction, in order to know the technical status of the bridge in time, take preventive measures. Therefore, it is very important for all units that conduct bridge inspection, management and maintenance to have a set of inspection and analysis system that can meet the needs of on-site timely, portable and accurate understanding of bridge vibration.
