现浇连续梁施工工艺

Construction Technique of Cast-in-situ Continuous Beam

目前,在铁路建设中,跨越河流、城市道路等障碍物的桥梁以连续梁形式为主,后张法预应力现浇连续梁凭借其施工周期短的优势在铁路桥梁建设中得到较广泛的采用。武汉天兴洲大桥南岸引桥(客运专线)跨越武汉青山区友谊大道处采用(32+48+32)m等截面连续箱梁,文章详细介绍了该段桥梁采用的分段现浇连续梁的施工工艺。

In railway construction, continuous beam is mainly adopted to the construction of bridges across rivers and roads currently, and post-tensioned pre-stressing cast-in-situ continuous beam is also widely applied owing to its short construction period. The paper expounds the construction technique, section cast-in-situ continuous beam when building north approach bridge of Tianxing Bridge across Youyi Road of Qingshan district of Wuhan with the section continuous box beam of (32+48+32).
