| 摘 要： | 天津富民桥为(157.081 86.4) m单塔空间索面自锚式悬索桥.通过对天津富民桥施工过程中主梁关键截面的应力跟踪测试及对测试应力数据的处理分析,掌握主梁在施工各阶段的结构受力情况.分析表明,主梁在施工过程中受力比较合理,基本处于受压状态,拉应力较小,均在安全控制范围内.

| Abstract: | Fumin Bridge in Tianjin is a single tower and spatial cable plane self-anchored suspension bridge with span arrangement(157.081+86.4) m.In the construction of the main girder of the Bridge,the structural force conditions of the girder at different construction stages were understood and controlled through tracing and measuring of the stress of the critical cross sections of the girder and also through processing and analysis of the measured stress data.The results of analysis show that the force conditions ... |
