    摘要:

    漳州战备大桥系国内首次采用的矮塔部分斜拉索桥。主塔上部设有内外钢管的圆弧形索鞍,两侧斜拉索出口处设抗滑锚具。斜拉索穿过内钢管对称锚固于梁体。索鞍处外包裹PE镀锌钢绞线为裸露,待施工完毕,内管和抗滑锚具内灌注环氧水泥砂浆。张拉施工采用两端对称同步张拉

    Abstract:

    Zhangzhou Battle Bridge is the first short tower partially cable-stayed bridge in China. The upper part of the main tower is equipped with a circular arc-shaped saddle of internal and external steel pipes, and anti-slip anchorage is provided at the exit of the cable-stayed cables on both sides. The cable is symmetrically anchored to the girder through the inner steel pipe. The outer wrapped PE galvanized steel strand at the cable saddle is bare, and when the construction is completed, the inner pipe and anti-slip anchorage are filled with epoxy cement mortar. Tensioning construction adopts symmetrical synchronous tensioning at both ends.
