摘 要: 在广州市内环路广佛出口放射线珠江大桥西桥的实际施工方案里,对制梁台座的位置作了后移,通过计算和分析,得出制梁台座后移这一变更对整个顶推施工过程的影响,并对制梁台座后移的施工方案的优点和不利之处作了归纳。 In the actual erection scheme for Zhujiang River West Bridge on the radial roads at the exit Guangzhou to Foshan on the Inner Ring Road of Guangzhou City, the position of the girder precasting bed used for incremental launching construction of the Bridge is varied by shifting the bed backward. In this paper, the influences from variation of shifting the bed on the whole process of the incremental launching construction are analyzed through computation, and comments on both the advantages and disadvantages of the varied erection scheme are made as well.
