| 摘 要： | 多跨连续梁桥在悬臂状态下,采用支架法现浇铰接段箱梁时,由于系统温度及温度梯度的存在,现浇段容易产生裂缝。合理分析温度对结构产生的影响,并采取有效的应对措施才能避免裂缝。文章以厄瓜多尔巴巴奥约河大桥的铰接段施工为例,研究温度处理方法及应对措施,为类似工程提供参考。

| Abstract: | While multi-span continuous bridge is in the cantilever state and the box girder of hinge section is been pouring concrete by bracket method,the pouring section easily causes crack because of system temperature and temperature gradient. Only can calculating appropriately the influence of temperature on the structure and taking effective measures prevent crack in construction.Using the construction of hinge section of R f o Babahoyo Bridge in Ecuador as an example,the paper aims to explore ways of temperature treatment and some countermeasures in hope of offering some experience to similar projects. |
