| 大跨預應力混凝土曲線連續(xù)梁橋施工過程控制關鍵問題研究(51 卷) |
| 英文標題 |
| Study on key problems in control over construction process of large-span prestressed concrete curved continuous girder bridge |
| 摘要 |
| 以長春長北立交（55+80+86+92+55） m大跨預應力混凝土曲線連續(xù)梁橋為工程背景，研究了平面曲率半徑對主梁豎（橫）向預拱度的影響、混凝土收縮徐變模式、摩阻系數(shù)對豎向預拱度的影響及0號塊處受力情況，可為以后類似橋梁的施工控制提供參考。 |
