近年来,大跨预应力混凝土连续梁桥悬臂浇筑法在大跨预应力混凝土连续梁桥施工中的广泛应用,优势愈演愈强,随着大跨预应力混凝土连续梁桥跨度的不断增加,施工控制难度也就越大,对施工质量要求也随之增高,问题也正是层出不穷。该文结合对施工控制的结构计算以及施工控制的内容和方法等进行了深刻细致的分析研究;并对其进行仿真分析,提出通过优化结构体系转换顺序的方法对以上问题进行解决分析。
In recent years, wide-span prestressed concrete continuous beam bridge cantilever placement method in the construction of large-span prestressed concrete continuous beam bridge, the advantages of more and more strong, with the continuous increase of span of prestressed concrete continuous beam bridges, The greater the difficulty of construction control, the higher the quality of construction requirements, the problem is also emerging. In this paper, the structural calculation of construction control and the contents and methods of construction control are analyzed in detail. The simulation analysis is carried out, and the above problems are analyzed and solved through the optimization of structural transformation order.
