箱型拱钢桥系列 / Box Arch Steel Bridge Series
钢箱拱桥是一种横跨于河流、峡谷或道路等地形障碍上的钢结构桥梁。它由拱形主体和箱形梁体构成,箱形梁体一般位于拱形主体内部,两者以节点相连,形成一个整体结构。
钢箱拱桥的拱体结构通常由多节箱形钢梁拼接而成,形成一个平面曲线形状。在拱体两端,通过斜撑或直立支撑与墩台相连接,形成平衡状态。整座钢箱拱桥的荷载自重被均匀地输送给桥墩上,从而减轻了桥面荷载,增强了桥梁的承载能力。
Steel box arch bridge is a steel structure bridge spanning terrain obstacles such as rivers, canyons or roads. It consists of an arched body and a box-shaped beam. The box-shaped beam is generally located inside the arched body. The two are connected by nodes to form an overall structure.
The arch structure of a steel box arch bridge is usually made up of multiple box-shaped steel beams spliced together to form a plane curve shape. At both ends of the arch, a balanced state is formed by connecting piers through diagonal supports or upright supports . The load self-weight of the entire steel box arch bridge is evenly transported to the piers, thereby reducing the load on the bridge deck and enhancing the bridge's load-bearing capacity.
