依托某特大跨径连续刚构桥，对营运期间桥梁的线形、主墩的竖向位移、主墩的偏位、伸缩缝的变形进行了分析研究。首先，明确了特大跨连续刚构桥监测的内容和方法，进而用有限元软件 Midas Civil2012对桥梁变形相关理论值进行了计算。随后，现场实测了桥梁变形相关的数据。最后，将现场桥梁线形、主墩的竖向位移、主墩的偏位、伸缩缝变形的实测值与理论计算值进行了对比分析，得出本桥基本处于正常的工作状态这一结论。通过对特大跨径桥梁的分析，可为同类桥梁提供依据，具有较好的实用价值。
依託某特大跨徑連續剛構橋，對營運期間橋樑的線形、主墩的豎嚮位移、主墩的偏位、伸縮縫的變形進行瞭分析研究。首先，明確瞭特大跨連續剛構橋鑑測的內容和方法，進而用有限元軟件 Midas Civil2012對橋樑變形相關理論值進行瞭計算。隨後，現場實測瞭橋樑變形相關的數據。最後，將現場橋樑線形、主墩的豎嚮位移、主墩的偏位、伸縮縫變形的實測值與理論計算值進行瞭對比分析，得齣本橋基本處于正常的工作狀態這一結論。通過對特大跨徑橋樑的分析，可為同類橋樑提供依據，具有較好的實用價值。

This paper studies the alignment of bridge,the vertical displacement of the pier,the offset of the pier and the deformation of the expansion joints based on an extra large span continuous rigid frame bridge.Firstly,the contents and methods of the extra large span continuous rigid frame bridge mo-nitoring are fixed,and then using the FEA software-Midas Civil 2012 calculates the theoretical value of the bridge deformation.Furthermore,the deformation data of the bridge is measured.Finally,the author compares and analyzes the theoretical data and practical data on alignment of bridge,the vertical dis-placement of the pier,the offset of the pier and the deformation of the expansion joints.It shows that the bridge is under normal working condition.The study of this paper provides the basis for continuous rigid bridge and it has good practical value.
