摘要
以黄延高速公路葫芦河特大桥施工为背景,介绍边跨现浇施工中,通过及时改变合龙顺序,缩短边跨现浇段长度,在边跨采用不平衡悬浇与托架现浇相结合的方法,成功解决了边跨高墩跨大的施工难题,为以后工程施工提出有益的探索。
Based on the construction of the Huluhe Extra Large Bridge of Huangyan Highway, this paper gives a brief introduction of the side-span cast-in-place technique. By changing the sequence of beam - folding in time, shortening the length of the cast - in - place beam of the side-span, combining the construction methods of unbalanced cantilever beam casting and bracket casting-in-place, the difficult problems of the construction of high and large side-span is successfully solved, which may provide instructive reference for other similar works.
