Based on qualitative analysis and comparison of several options for suppressing transverse vibration on deck type steel plate girder of railway bridge, conclusions are made as follows : with static reinforcing, the vibration amplitude can be suppressed to some extent, but quasi - resonance of the bridge can not be avoided, moreover, the construction is inconvenient and costly. with option of two bridge connection, the effectiveness of vibration suppression is clear ( the damping ratio approaches 50 % ) and it is fairly economic and easy, however, the quasi - resonance of the bridge can not be avoided either. with dynamic option ( mtmd option ), the quasi - resonance of the bridge can be effectively avoided ( the damping ratio is up to 51. 38 % as tested in field ), moreover, the construction cost is low, and the construction is simply and convenient
通過對目前抑制鐵路上承式鋼板梁橋橫向振動的幾種方案進行定性的分析和比較，認為：靜力加固方案可以使橋梁振幅有所減小，但不能避免準共振現象的發生，而且工程造價較高，施工也不方便；兩橋連接方案減振效果明顯（減振率近50 % ） ，比較經濟也比較方便，但同樣不能避免準共振現象的發生；動力減振方案（ mtmd抑振方案）可以有效的抑制橋梁的準共振現象（現場試驗中減振率達51 . 83 % ） ，而且工程造價較低，施工簡單、方便。 -
