预应力砼部分斜拉桥鞍座部分应力分析

Stress Analysis of Partially Cable-stayed Prestressed Concrete Bridge with Cable Saddles Structure

利用ANSYS大型分析软件对一单索面预应力混凝土部分斜拉桥桥塔部分进行了三维有限元计算 ,着重对索鞍这一局部结构进行了应力分析 ,对原设计提出了若干建议 。

In this paper, solid element of the finite element program is used to analyze the tower of a partially cable stayed prestressed concrete bridge. Furthermore, the stress distribution of the tower saddles is studied with the finite solid element method, which is of practical significance for the design and construction of this kind bridge.
