空间缆索人行悬索桥索鞍设计研究

Study on Design of Cable Saddles for Spatial Cable Pedestrian Suspension Bridge

以淳安上江埠骑行桥为工程背景,介绍了空间缆索人行悬索桥索鞍的构造设计,通过计算分析阐述空间缆索悬索桥索鞍的受力特性,分析结果表明空间缆索悬索桥主缆在平弯效应下对索鞍产生横向力作用,外侧壁应力大于内侧壁,故在设计时可对外侧壁进行加强,可为同类桥梁设计提供参考。

Under the engineering background of the pedestrian bridge at Shangjiangbu of Chun'an,the construction design of the cable saddles for spatial cable pedestrian bridge is introduced.The stress characteristics of the cable saddles for spatial cable suspension bridge are expounded by the calculation and analysis.The analysis result shows that the main cable of spatial cable suspension bridge will produce the horizontal force action on the cable saddles under the flat bending effect.The stress of the outer wall is greater than that of the inner wall.Therefore,the outer wall can be reinforced during the design,which can be referred for the design of the similar bridges.
