| 標(biāo)題 |
| 既有PC斜拉橋的主梁橋面線形調(diào)整實踐(49 卷) |
| 英文標(biāo)題 |
| Practice on adjusting of line-shape of bridge deck consisting of main girders on existing PC (Prestressed Concrete) cable-stayed bridge |
| 摘要 |
| 當(dāng)PC斜拉橋運營一段時間后，主梁線形常常發(fā)生改變，此時通過索力調(diào)整來改善主梁線形是有效的技術(shù)途徑之一。以國內(nèi)某PC斜拉橋為工程背景，介紹了PC斜拉橋主梁線形調(diào)整的基本方法。對比分析當(dāng)前結(jié)構(gòu)狀態(tài)與原橋竣工線形、索力等的差異基礎(chǔ)上，確立了主梁線形調(diào)整的目標(biāo)和索力調(diào) |
