摘　　要：结合秦沈客运专线和其它国家或地区高速铁路桥型的选择 ,对京沪高速铁路中小跨度桥梁的刚度、造价等方面进行分析 ,结论是箱形截面梁性能优于T梁 ,在地基条件好的区段连续梁优于简支梁。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.
