【Introduction】
In a systematic and comprehensive historical survey of bridges in China, A Guide to Chinese Bridges features over 300 ancient bridges and nearly 1000 modern bridges. On the one hand, the book presents the notable successes of the ancient Chinese; on the other hand,it reflects the rapid progress and brilliant achievements in bridge construction in the later half, especially in the last decade, of the 20th century.
The techniques employed in ancient Chinese bridges, especially the arch bridge represented by Zhaozhou (Anji)bridge, have provided a foundation for the development of the modern Chinese arch bridge. This is exemplified by Chyinese masterworks that match comparable record-breaking spans around the world such as Danhe Bridge in Shanxi Province(stone arch bridge),Wanxian Yangtze Bridge in Chongqing Municipality (reinforced concrete arch bridge)and Yajisha Zhujiang (Pearl River) Bridge in Guangdiong Province (concrete-filled steel-pipe arch bridge).They share a heritage based in the creativity and development of ancient techniques in Chinese arch bridge construction.
While respecting its roots in ancient Chinese bridge construction and design, modern China has also made a point of employing the best construction techniques from other countries, something that helped bring many "rainbows"to the great land of China in the late 20th century. A series of continuous rigid-frame long-span bridges were constructed with prestressing techniques such as the Humen bridge across the Pear river in Humen, Guangdong Province. Nearly 100 cable-stayed bridges and suspension bridges, represented nationwide by the No.2 Nanjing Yangtze River Bridge and Jiangyi Yangtze River Bridge, adopted cable supporting techniques.These major projects combined both Chinese and new world technologies.
