摘要
城市高架曲线钢箱梁桥道路中心线一般为空间多维曲线,结构形式复杂,施工详图设计难度较大。以武汉市二环线汉口段EL5联钢箱梁桥为例,重点从桥面线形放样、曲面展开、重心计算等方面介绍钢箱梁桥的施工详图设计方法,为类似工程提供可借鉴的经验。
Generally,the street center line of curve steel box beam bridge for city overhead is space multidimensional curve,type of construction is complicated,construction detail design has large difficulty.Take the EL5unit steel box beam bridge of Hankou section of Wuhan second circle line for example,from bellow key point introduce the construction detail design,such as linear lofting of bridge deck,develop of curved surface,calculate the center of gravity,which can provide refer for similar project in future.
