在陕西安康水电专用线上,跨越汉江的我国第一座钢斜腿刚构铁路桥,于1982年12月28日建成通车。该桥两腿铰中心的间距176米;为世界上跨度最大的铁路钢斜腿刚构桥。因采用薄壁箱型钢梁与钢箱型斜腿的组合结构,较同跨度同钢种的桁架桥可节约钢材42％。这座桥的建成为我国铁路钢桥增添了新的结构形式,经重车及双机连挂运转,结构工作状态良好。 1982年12月21—24日中国铁道学会在安康汉江桥
On the Ankang hydropower special line in Shaanxi Province, the first steel-framed rigid-framed railway bridge across the Han River in China was opened to traffic on December 28, 1982. The hinge distance between the two legs of the bridge is 176 meters; it is the largest span steel rigid frame bridge in the world. Due to the combined structure of thin-walled box girder and steel box-type oblique leg, the steel material can be saved by 42% compared with the same type of truss bridge with the same span. The construction of this bridge has added a new structural form to the railway bridge in our country. After the operation of heavy vehicles and double engines, the structure works in good condition.
