悬索桥结构是跨度最大的桥梁结构,在基础施工困难的水域或沟壑地区,悬索桥可以一跨跨越。由于横向、竖向刚度相对较弱,铁路桥梁中未采用悬索桥结构。悬索桥的结构形式现代悬索桥跨度一般在600m以上,主要由索塔、锚碇、主缆、吊索、加劲梁组成。小跨度悬索桥可以采用自锚方式,不设置体外锚碇,一般采用支架法施工。图1为悬索桥。
Suspension bridge structure is the span of the largest bridge structure, in the basic construction of difficult water or ravine, the suspension bridge can span across. As the horizontal and vertical stiffness is relatively weak, the suspension bridge structure is not used in railway bridges. Suspension Bridge Structure Modern suspension bridge span of more than 600m, mainly by the pylon, anchor 碇, the main cable, sling, stiffening beam composition. Small-span suspension bridge can be self-anchored, not set in vitro anchorage, the general use of stent construction. Figure 1 shows the suspension bridge.
