【Abstract】 To test boom tensions with vibration frequency method is to analysis vibration characters of the boom, then to get the boom tensions. Testing method and results of Qingchuan Bridge by vibration frequency method are introduced. The entire boom tensions of the bridge are analyzed, which are all within allowing ranges. The method is feasible.更多还原
