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.
以结构力学为基础，利用加固前对钢板梁桥测得的横向位移，提出了一种通过反算出列车等效横向摇摆力来计算加固后钢板梁桥的横向位移的方法。
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.
针对某板梁桥的病害形式，采用了翻新桥面铺装和施加横向预应力的加固技术。
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.
本文的分析结果可为解决我国铁路提速后钢板梁桥横向振动问题提供理论参考。
