When resonance kills: the Angers Bridge • Science Chamber of Horrors
链接里的文章对此事来龙去脉讲的很清楚。就本题而言:
1,军队齐步走,对桥来说很危险(因为可能发生共振而造成严重影响)。
2,没有那座桥完全是因为军队齐步走震塌的,链接里提到的两座桥都是吊桥(有图)。
It should be noted that neither the Angers Bridge nor the Broughton Bridge collapsed entirely due to the actions of the soldiers. Both bridges were determined to have maintenance and engineering problems that made collapse inevitable; the marching exacerbated existing weaknesses.
ps:港剧《回到三国》里也用了这个桥段,是一座数米长的石拱桥,士兵十数人,张飞喝断当阳桥......
