专业设计院负责设计的某专用线汉江斜腿刚构桥,目前已进入紧张架设施工阶段。该桥是我国第一孔薄壁钢箱形结构的斜腿刚构铁路桥,主梁为五跨连续梁,按56+64+64+64+56米分跨,钢梁全长305.1米,斜腿倾角为42°53′,两斜腿铰中心间跨距为176米。该梁一跨跨过汉江,以避免修建水中高墩,节省了钢材及圬工,降低了造价,缩短了建桥工期。该桥由铁科院负责研究试验,宝鸡桥梁厂制造,铁一局施工。根据桥址地形条件,采用了 Professional Design Institute is responsible for the design of a special line Hanjiang inclined leg rigid frame bridge, has now entered the stage of intense construction. The bridge is China’s first hole thin-walled steel box-type structure of the oblique leg rigid-frame railway bridge, the main beam of five-span continuous beam, according to 56 +64 +64 +64 +56 m points span, a total length of 305.1 meters of steel beams, 42 ° 53 ’, two skewed leg hinge center span of 176 meters. The beam spans across the Han River, in order to avoid the construction of high-pier in the water, saving the steel and labor, reducing costs and shorten the construction period. The bridge is responsible for research by the ASTRI, Baoji Bridge factory manufacturing, a railway construction. According to the bridge topography conditions, adopted
