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。 -
During the finite element modeling of the bridge, the factors affecting the accuracy of the finite element model are discussed in detail, such as, the geometrical non - linearity of the cable including gravitational sag and initial tension, and the structural orthotropic steel box - girder deck to be equivalent to physical orthotropic deck by using compound material mechanics, and so on
在建模過程中，盡可能多地考慮了一些影響全橋有限元模型精度的因素：如斜拉索的幾何非線性（重力垂度和初始應力） ，將構造正交各向異性鋼箱梁橋面板用復合材料力學的方法等效為物理正交各向異性板等。 -
