摘要 文章以某矮塔斜拉箱梁桥的悬臂施工过程控制为研究背景,通过对其进行24h温度监测,总结大气温度、梁体温度与悬臂段标高和关键控制截面应力变化规律,能够较好地修正温度和桥梁线形之间的关系,为之后施工节段的立模和梁体最终合拢提供有价值的参考依据。 With the cantilever construction process control of a low-tower cable-stayed box girder bridge as research background, through its 24h temperature monitoring, this article summarized the atmospheric temperature, beam temperature, cantilever section elevation and key control section stress variation law, which can better adjust the relationship between temperature and bridge linearity, thereby providing the valuable reference for the final closure between the beam and the mold in subsequent construction segments.
