| 城际轨道大跨度连续梁桥线形监控研究(52卷) |
| 英文标题 |
| Research on line shape monitoring of large-span continuous girder bridge in urban mass transit system |
| 摘要 |
| 以广珠城际轨道某大跨度连续梁桥为例，在确定仿真计算参数以及考虑诸多相关影响因素的基础上，着重考虑荷载因素进行仿真计算，得到各控制截面的控制点预拱度值，从而确定桥梁结构施工过程中每个阶段的理想变形状态；以此为依据来控制施工过程中每个阶段的结构行为，以确保施工中结构的可靠性与安全性，保证成桥后桥梁线形符合设计要求。 |
