探讨钢丝绳在悬索桥上的应用

钢丝绳逐渐在人行悬索桥上广泛应用,但由于钢丝绳相对平行钢丝索股的弹性模量偏小,给设计及施工带来一系列的问题,本文结合南平九峰索桥的实际应用,分别介绍了吊杆、主缆索股、索夹和索鞍的设计思路及注意事项。并结合该桥的施工方法和步骤做了进一步的说明,对类似悬索桥的设计及施工具有一定的参考意义。

The application of wire rope in suspension bridge is discussed

Wire rope is gradually widely used in pedestrian suspension bridge, but because the elastic modulus of wire rope is relatively small compared with the parallel wire rope strand, it brings a series of problems to the design and construction. Combined with the practical application of Nanping Jiufeng cable Bridge, this paper introduces the design ideas and precautions of the derrick, main cable strand, cable clip and cable saddle respectively. Combined with the construction methods and steps of the bridge, it is further explained, which has certain reference significance for the design and construction of similar suspension Bridges.
