摘要
京秦通道提速改造速度为 160～ 2 0 0km/h。通过对主要技术标准的研究、实车试验、动力仿真计算等提出既有桥梁利用、改建、加固的意见 ,并对梁部结构的加固方案进行初步验证。
The proposed speed on Beijing\|Qinhuangdao Railway after speed increase is 160～200km/h. A proposal is given on the use, rebuilding and consolidation of existing bridges through study on primary technical standards, trial run and dynamic simulation computation. A preliminary examination of girder strengthening program was conducted.
