悬索式管桥是长输管道跨越中常用的一种形式，其结构主要由主索、抗风索、塔基和锚固系统及梁式管桥等部分组成。
Suspension pipe bridge is a kind of common structural form consisted mainly of main cable wind cable tower foundation anchor system and girder form pipe bridge.
在悬索桥的抗风设计中，流线型箱梁由于具有较好的抗风性能而得到广泛应用。
In the process of wind-resistance design of suspension Bridges, streamlined box girder has been widely applied because of its better wind-resistance performance.
风洞节段模型试验结果表明：主梁具有很好的抗风稳定性。
It is proved that the main truss has excellent wind stability through the wind tunnel test of section model.
悬索桥服役一段时间以后，在风荷载的作用下将造成主要构件加劲梁抗弯刚度的削弱进而导致结构损伤。
After a period of service time, the moment rigidity of the stiffening beam for a suspended bridge will be impaired under the wind load, which will lead to the structural damage.
