人类最初架在小河之上的桥是用木头,绳索和石头等材料简单架构起来的。后来用一些更结实耐用的材料替代了它们,比如钢铁、水泥等。古老的桥梁建筑术发展至今,技术上更加完善,表现形式更趋于多样,新科技力量的注入,使得全球涌现出一批让人叹为观止的工程奇迹,如今的桥梁已经不单是一种交通设施,而是一门艺术,一道景观。
The bridge from which human beings originally stood on the stream was simply constructed of materials such as wood, ropes and stones. Later they replaced them with more durable materials such as steel and cement. The development of the ancient bridge construction so far, more technologically perfect, more diverse forms of performance, the influx of new scientific and technological forces, making the emergence of a number of impressive global engineering miracle, the bridge is now not only a transportation infrastructure, It is an art, a landscape.
