| 既有線32 m下承式鋼板梁加固方案的車—橋動(dòng)力仿真分析(29 卷) |
| 英文標(biāo)題 |
| Analysis on Train-Bridge Dynamic Simulation for Reinforcement of the 32 m Through Steel Plate Girders on Existing Line |
| 摘要 |
| 為配合滬寧線250 km·h-1 提速改造工程，運(yùn)用車橋耦合振動(dòng)方法，從車輛和橋梁動(dòng)力響應(yīng)角度，對(duì)一撓跨比、跨中梁體橫向振幅及橫向加速度均超過《鐵路橋檢規(guī)》通常值的32 m下承式鋼板梁進(jìn)行加固方案比選。車—橋仿真計(jì)算結(jié)果表明加強(qiáng)主梁可以明顯提高橋梁的豎向剛度和橫向剛度 |
