| 寬幅箱梁懸臂施工控制關(guān)鍵技術(shù)的探討(51 卷) |
| 英文標(biāo)題 |
| Discussion on key control technology during cantilever construction of widened box-girder |
| 摘要 |
| 預(yù)應(yīng)力混凝土連續(xù)梁橋橋跨布置為（47+80+47）m，主梁采用單箱雙室箱形截面，三向預(yù)應(yīng)力體系。本文就寬幅箱梁懸臂施工控制中的掛籃變形控制、梁體剪力滯效應(yīng)測試、梁體合龍順序等關(guān)鍵技術(shù)進(jìn)行了分析和探討，通過采取相應(yīng)的技術(shù)措施保證了橋梁施工安全。 |
