近几年来,伴随着国内经济水平的不断提高,我国对于桥梁等基础设施的建设越来越重视。在进行连续刚构桥的施工过程中,经常会用到的一种施工方法就是悬臂浇筑施工法。在进行悬臂浇筑施工时,最重要的施工任务之一就是控制好桥梁的挠度,这就要求设计人员以及计算人员进行仔细、科学的计算。本文结合梧柳高速下路柳江特大桥的施工案例,对连续刚构桥悬臂施工浇筑挠度的影响因素以及控制措施进行探讨。
In recent years, with the continuous improvement of the domestic economic level, our country pays more and more attention to the construction of bridges and other infrastructure. In the continuous rigid-framed bridge construction process, often used in a construction method is the cantilever casting construction method. One of the most important tasks in cantilever construction is to control the deflection of the bridge. This requires careful and scientific calculations by designers and calculators. In this paper, combined with the construction of the Liuliu Bridge under the Wuluo Highway, the factors that affect the pouring deflection of cantilever construction of continuous rigid frame bridge and the control measures are discussed.
