摘要
通过321型贝雷梁在宁波轨道交通1号线二期工程简支箱梁支架施工中的多种应用,根据施工条件分别设计了双层、单层设有中支墩、及单层加强HD200型钢桁梁等各类型梁柱式支架。详细介绍了贝雷梁施工支架的设计,采用合理的计算理论、模型进行了理论分析及结构安全计算,以期为今后现浇梁桥的设计及施工积累经验。
By type 321 bailey beam in ningbo rail transit line 1 in the second phase of the simply supported box girder bracket construction a varietyo fapplicafions, according to the construction conditions respectively designed double and single sets of piers, and single strengthen HD200 steel truss beam and so on various types Liang Zhushi stents. Bracket of bailey beam was introduced in detail the construction design, the reasonable calculation theory, the model is used for theorotical analysis and the structural safety calculation, so as to the future of cast-in-place girder bridge design and construction experience.
