Key Sling Saddle Design Points of Kaizhou Lake Bridge in Guiyang

摘要:

散索鞍是设置在锚碇支墩顶部的重要受力构件,它的工作正常与否直接关系到大桥的安全。以瓮安至开阳高速公路开州湖大桥为工程背景,详细阐述了国内悬索桥首次设计采用的分体式散索鞍结构。该新型散索鞍结构为同类桥梁设计提供了新思路。

Abstract:

The sling saddle is an important component installed on the top of the anchor pier. Its normal operation is directly related to the safety of the bridge. Taking the Kaizhou Lake Bridge in Wengan to Kaiyang Expressway as the engineering background, the separated structure of sling saddle firstly used in the design of the domestic suspension bridges is expounded in detail. The new type of sling saddle structure provides a new idea for the design of similar bridges.
