摘要
简述了预应力混凝土连续梁桥施工中的高程控制及高程控制的重要性,考虑混凝土徐变、利用有限元法建立了悬臂挠度计算模型,并得出了计算结果与实测结果较吻合的结论,可为桥梁高程控制提供参考。
This paper illustrates height control in pre-stressed concrete continuous beam bridge construction and its importance,establishes computing model of cantilever deflection by finite element method considering the creep of concrete,and draw a conclusion that the computing result is rather identical with that of field measurement,which to offer a reference for the control of bridge height.
