General Design of Fuzhou-Xiamen High-speed Railway Bridges

In order to promote the rapid development of the HAIXI Economic Circles, the new railway from Fuzhou to Xiamen is designed; speed is 350 km/h, the whole line of the railway adopt ballastless track. Along the railway line,the natural environment such as topography, geology, hydrology and meteorology is complex.The railway cross a lot of bays、 riverways、 highways and railways. There are many special long-span bridges and the bridges account for 65% line length. The article mainly introduces the construction condition、 design principle, the main technical characteristic and Design of six long-span cable-stayed bridges. Following the principles of "safety, practicality, economy and beauty", This railway will innovate and enrich the technology of high speed railway bridge in our country. The practice of this project will accumulate experience for the construction of high speed railway in China.
