China's Major Bridges

Abstract

<p>In response to continuous economic development over the past 30 years, China has mobilized a program of large scale bridge construction. The technology of various types of bridges , including girder bridges, arch bridges, and cable-supported bridges , has been developed rapidly. Bridge spanning capacity has been continuously improved. Girder bridges with main span of 330 m, arch bridges with main span of 550 m, cable-stayed bridges with main span of 1 088 m and suspension bridges with main span of 1 650 m have already been built. Moreover, two sea-crossing bridges with overall length over 30 km have also been opened to traffic. This paper briefly introduces China' s major bridges, including girder bridges with spans greater than 200 m, arch bridges with spans greater than 400 m, cable-stayed bridges with spans greater than 600 m, and suspension bridges with spans greater than 1 200 m. These bridges represent technological progress in such aspects as structural system, materials, as well as construction methods and equipment.</p>
