在不同的历史时期,中国建造的众多铁路钢桥及相应的设计,阐述了中国铁路桥梁发展的艰辛历程,证明了中国铁路钢桥的发展已经有了很大进步,但同时建设中出现的车桥耦合共振、钢材高强等一系列问题表明,中国要想要进入世界铁路钢桥建设的前列,仍需不断努力。 In different historical periods, many railway steel bridges built in China and the corresponding design elaborated the difficult course of the development of the railway bridges in China, and proved that the development of the railway bridges in China has made great progress. However, at the same time, Bridge Coupling Resonance, Steel Strength and a series of questions show that China wants to enter the forefront of the world's railway steel bridge construction, still need continuous efforts.
