| 城際軌道大跨度連續(xù)梁橋線形監(jiān)控研究(52卷) |
| 英文標(biāo)題 |
| Research on line shape monitoring of large-span continuous girder bridge in urban mass transit system |
| 摘要 |
| 以廣珠城際軌道某大跨度連續(xù)梁橋為例，在確定仿真計算參數(shù)以及考慮諸多相關(guān)影響因素的基礎(chǔ)上，著重考慮荷載因素進(jìn)行仿真計算，得到各控制截面的控制點預(yù)拱度值，從而確定橋梁結(jié)構(gòu)施工過程中每個階段的理想變形狀態(tài)；以此為依據(jù)來控制施工過程中每個階段的結(jié)構(gòu)行為，以確保施工中結(jié)構(gòu)的可靠性與安全性，保證成橋后橋梁線形符合設(shè)計要求。 |
