| 既有重載鐵路墩梁加固分析(50 卷) |
| 英文標(biāo)題 |
| Analysis on strengthening of bridge pier and girder on existing heavy haul railway |
| 摘要 |
| 針對(duì)大秦線運(yùn)量不斷增加后出現(xiàn)的簡(jiǎn)支梁、中高橋墩橫向自振頻率偏低、振幅過大的情況，對(duì)梁、墩進(jìn)行有限元分析，通過比選提出合理的加固方案。加固前后結(jié)構(gòu)動(dòng)載試驗(yàn)表明，通過加固可以有效改善結(jié)構(gòu)的動(dòng)力性能，能夠滿足《鐵路橋梁檢定規(guī)范》的要求，保證列車安全運(yùn)營(yíng)。 |
