斜拉橋
维基百科,自由的百科全书
斜拉橋又稱斜張橋是由一組或多於一組的鋼纜支持著橋面的橋。斜拉橋主要分為兩大類,主要分辨要視乎鋼纜是怎樣與橋塔連接。平行連接款式, 鋼纜與橋面和橋塔the cables are made nearly parallel by attaching cables to various points on the pillar so that the height of attachment of each on the pillar is similar to the distance from the pillar along the roadway to its lower attachment. In a 放射性連接 design, the cables all connect to or pass over the top of the pillar.
The cable-stay design occupies a w:en:sweet spot of length between 懸臂橋和懸索橋 . Within this sweet spot a suspension bridge would require lots more cable, while a full cantilever bridge would require considerably more material.
