摘　　要：仪陇县嘉陵江三桥主桥形式为(120+230)m拱形斜塔钢混组合斜拉桥,主梁采用双边箱钢混组合箱梁,全宽40m;桥塔采用钢混组合倾斜桥塔,塔柱正面为拱形结构,线形为椭圆曲线。采用Midas Civil有限元软件进行整体验算,结果表明,大跨度拱形斜塔钢混组合斜拉桥受力满足相关规范要求。The main bridge of the No.3 bridge over Jialing river in Yilong county is a(120+230)m steel-concrete composite cable-stayed bridge with arched inclined pylon.The bilateral box steel-concrete composite box girder is adopted for the main beam,with a total width of 40m.The steel-concrete composite inclined pylon is adopted for the bridge,and the front of the pylon column is an arched structure with a shape of elliptical curve.The overall verification is carried out by using the Midas Civil finite element software.The result shows that,the stress of the large-span steel-concrete composite cable-stayed bridge with arched inclined pylon meets the requirement of relevant specification.
