| 既有鐵路橋梁重載改造技術(shù)研究與應(yīng)用(51 卷) |
| 英文標(biāo)題 |
| Study and application of technology on transforming existing railway bridge into heavy haul one |
| 摘要 |
| 通過對大秦鐵路年運(yùn)量400 Mt條件下橋涵結(jié)構(gòu)的研究，指出我國既有鐵路橋涵進(jìn)行重載改造存在的主要問題，從對典型橋加固改造方案的計(jì)算分析結(jié)果可以看出，采用合理的強(qiáng)化措施后，我國既有鐵路橋涵可以滿足重載運(yùn)輸大軸重、高密度、大運(yùn)量的運(yùn)營要求。 |
