叠合梁斜拉桥0~#钢梁托架的设计与应用

Design and Application of 0~# Steel Girder Bracket for Cable-Stayed Bridge with Composite Beams

在斜拉桥的施工中,临时支架结构的合理设计是桥梁工程施工的基本条件和保障。遵余湘江大桥是一座双塔双索面叠合梁斜拉桥,在其现场条件下,具有一定的特殊性。结合该桥0#节段施工临时支架的设计、验算及施工过程中应注意的要点,总结了类似0#节段支架设计与施工的经验。

In the construction of cable-stayed bridge,the reasonable design of temporary bracket structure is the basic condition and guarantee of bridge construction.The Zunyu Xiangjiang bridge is a cable-stayed bridge with double pylons and double cable planes,which has certain particularity under its field conditions.Combined with the design,checking calculation and key points in construction of temporary bracket for 0~#section construction of the bridge,the experience of design and construction of similar 0~#section bracket is summarized.
