In the paper, one of the finite element analytical models for spatial vibration of the train and deck steel plate girder bridge system is presented. 以結(jié)構(gòu)力學(xué)為基礎(chǔ)，利用加固前對(duì)鋼板梁橋測(cè)得的橫向位移，提出了一種通過(guò)反算出列車(chē)等效橫向搖擺力來(lái)計(jì)算加固后鋼板梁橋的橫向位移的方法。
Aiming at overcoming the defects of a certain plate girder bridge, the technique of renewing the deck pavement and the transversely pre-stressing technique are adopted. 針對(duì)某板梁橋的病害形式，采用了翻新橋面鋪裝和施加橫向預(yù)應(yīng)力的加固技術(shù)。
The conclusion in this paper could be a meaningful theory reference for the transverse vibration problem of deck steel plate girder bridge, with the increasing of train speed in our country. 本文的分析結(jié)果可為解決我國(guó)鐵路提速后鋼板梁橋橫向振動(dòng)問(wèn)題提供理論參考。
