摘要
对预应力混凝土连续箱梁在施工阶段各工况下0#块顶板、底板、腹板和横隔板作了空间应力分析,计算中计入了收缩、温度和时间效应的影响,对不同施工阶段作了对比分析,计算结果为该桥的设计提供了依据,对于同类桥梁0#块设计也具有重要的参考价值。
This paper makes a comprehensive analysis of segment No. 0 of the continuous box girder bridge, including analysis of 3D stress on the deck, web and bottom plate of the segment. Since shrinkage, temperature and time-dependent effects are considered during the calculation of 3D stress. The result of this paper provides experience for design of the bridge and offers important reference value to segment No. 0 design of the same kind bridge.
