大桥是跨越空间的纽带,它能让汽车、火车、管道和人类轻松地通过各种障碍物。不管是复杂的钢索系统,还是简单的拱型建筑,大桥在被设计建造时,设计者都必须特别仔细,因为一座大桥不仅需要支撑自己的重量,还需要承受过往车辆的重量。大桥还必须能够承受强风、冰冻,甚至是地震的考验。
The bridge is a space-bound link that allows cars, trains, pipes and humans to easily pass through a variety of obstacles. Whether it’s a complicated cable system or a simple arched building, the designer must be careful when designing the bridge because a bridge needs to support not only its own weight but also the weight of passing vehicles. The bridge must also be able to withstand strong winds, freezing and even earthquake tests.
