On selection of types of small and medium span bridges on Beijing-Shanghai High Speed Railway

Based on bridge type selection of Qinhuangdao\|Shenyang Passenger Special Line and of high speed railways of other countries and regions, the paper analyzes the stiffness and cost of small and medium span bridges for the proposed Beijing\|Shanghai High Speed Railway. Result shows that, box girder presents better performance than T beam, and continuous girder is better than simple support girder in sound ground conditions.
