重庆市江津观音岩长江大桥索塔锚固区受力分析

Stress Analysis of Cable Tower Anchoring Zone of Guanyinyan Yangtze River Bridge in Jiangjin,Chongqing

运用杆系有限元分析软件和空间有限元分析软件对重庆市江津观音岩长江大桥进行索塔锚固区受力分析,通过实际分析计算,对索塔井字形预应力锚固区的受力机理进行一定的剖析,根据索塔的受力实际工况,给出结构特征点处的应力值,为设计施工提供参考。

Linear finite element analysis software and space finite element analysis software are utilized in anchorage zone force analysis of Jiangjin Guanyinyan Yangtze River Bridge.Through practical analysis and calculation,this paper discusses stress mechanism of cable supported tower groin prestressed anchorage zone.Based on the actual stress condition of cable supported tower,stress values for structural characteristic points areprovided,which may be useful for actual construction.
