摘要
针对某三跨悬臂施工连续梁桥的工程情况,就合拢块的施工方案确定和施工步骤的实施过程做了具体阐述。介绍了该桥合拢段施工时刚性支撑骨架的安装、合拢段锁定、混凝土浇筑等施工工艺,并进行了合拢段刚性支撑骨架在温度作用下的受力分析。
According to the engineering case of a three span continuous bridge with cast-in-place cantilever construction method,the construction method and construction program of closing segment are described in this paper.The construction technology such as the installation for rigid support frame and the fixing for closing segment,and the cast-in-place technology of concrete are also described in detail.The inner force of the rigid support frame under temperature load are specially analyzed.
