plate girder bridge

基本解释

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.
以結搆力學爲基礎，利用加固前對鋼板梁橋測得的橫曏位移，提出了一種通過反算出列車等傚橫曏搖擺力來計算加固後鋼板梁橋的橫曏位移的方法。
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.
針對某板梁橋的病害形式，採用了繙新橋麪鋪裝和施加橫曏預應力的加固技術。
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.
