某连续梁桥合拢段临时锁定体系的设计计算

摘要

The construction of closure joint is a key technique among the cantilever construction of continuous beam, because the closure joint needs to be locked. According to the mechanical features of closure joint of bridge's central segment, the formulas with on actual bridge of cantilever construction under different temperature conditions were analyzed. The calculation process can provide the reference for technical staffs who need rapid calculation.%连续梁悬臂施工中,合拢段施工是关键,施工前需要临时锁定合拢段.针对中跨合拢段的受力特点,根据力学知识列出计算公式,结合实际悬臂施工的桥梁,按照不同的温度条件进行理论计算,得到实际结果,并对结果进行分析.此计算过程可以为技术人员进行快速计算提供参考.
