Development and Practice of High-speed Railway Bridge Technology in China

The rapid development of high-speed railways in China has promoted the rapid improvement of high-speed railway bridge technology.The development history and achievements of high-speed railway bridges in China are reviewed,and new technologies of high-speed railway bridge in China are discussed.The development of high-speed railway bridges technology in China are analyzed and summarized in terms of standard-span simply-supported box girder construction,creep control and limit span of long-span concrete bridges,concrete beam arch composite structure,ballastless track technology for long-span bridges,technology for long-span steel bridges and arch bridges,the application of the cable-stayed bridges and suspension bridges in railway.Development direction and approach of high-speed railway bridge construction with Chinese characteristics,such as research on new materials and new equipment,are put forward in this paper.
