摘要
塔科马大桥建成仅4个月就坍塌毁掉了。坍塌的主要原因是风致颤振,此外,还有许多其他形式的解释。本文从设计、建设、坍塌过程、事故调查、科学家针对大桥的各种研究等方面对大桥坍塌的原因进行了简明的介绍,并总结了事故对之后大桥设计与建造的启示。
The Tacoma Narrows Bridge collapsed just four months after its completion.The main cause of the collapse is wind-induced flutter.In addition,there are many explanations.This paper briefly introduces the causes of the collapse from the aspects of design,construction,collapse process,accident investigation,and various scientific researches on the bridge,and it also summarizes the enlightenment of the accident on the design and construction of bridge after the accident.
