| 標(biāo)題 |
| 新菏線跨京廣鐵路特大橋抑振加固實(shí)踐(51 卷) |
| 英文標(biāo)題 |
| Reinforcing practice in vibration-restraining of super-large bridge on Xinxiang-Heze railway over Beijing-Guangzhou line |
| 摘要 |
| 對新菏線跨京廣鐵路特大橋雙柱式橋墩振動異常進(jìn)行分析表明，橋墩墩身結(jié)構(gòu)及軟弱地基都可能會導(dǎo)致墩頂振幅過大。加固實(shí)踐證明，單獨(dú)加固基礎(chǔ)或墩身都不能有效地抑制墩頂振動，對二者同時進(jìn)行加固才能夠達(dá)到預(yù)期的效果。 |
