摘要
对某立交桥采用重量轻、刚度大的钢悬臂梁进行了拓宽设计,通过预应力钢绞线连接钢结构与混凝土结构,不需要增加额外的桥墩,也不会影响桥下交通,该方法可以在同类桥梁设计中加以推广应用。
On a certain overpass by light weight, stiffness of the steel cantilever beam widening design, the connection of steel structure and concrete structure is by prestressing steel-cable. It does not need additional piers, and also won＇ t affect the traffic under the bridge. It is proved that the technology can be used in the same kinds of bridges design.
