悬索桥索夹滑移影响分析

Influence Analysis of Cable Clamp Slip on Suspension Bridge

通过对悬索桥主缆线形、索塔偏位、吊索垂直度、桥面线形的数据分析,评估索夹滑移对结构变位的影响。实测索力对比成桥索力,滑移的吊索索力减少、相邻吊索索力增大。建立有限元模型模拟索夹滑移,分析索夹滑移前后桥梁各构件的受力情况。

The impact of cable slip on structural dislocation was assessed by analysing data on the linear shape of the suspension bridge main cables,cable tower deflection,cable verticality and deck alignment.The measured cable forces were compared to the bridge cable forces,with the slipping cable force decreasing and the adjacent cable force increasing.A finite element model was developed to simulate the slip of the cable clamp and analyse the forces on the bridge elements before and after the slip of the cable clamp.
