大跨径预应力混凝土连续梁桥设计研究

Research on large span PC continuous beam bridge design

结合一座预应力混凝土连续梁桥的设计为背景,对箱梁截面形式选取、结构尺寸拟定、预应力钢束布置方式等设计要点进行了研究。借助有限元分析软件,对上部结构进行了分析计算,设计成果合理,满足规范要求。

Based on a pre-stressed concrete continuous beam bridge,this paper carried out research on section type selection,structural dimension draft,prestressed tendons arrangement and so on.With the help of finite element method software,it conducted calculation and analysis on the superstructure,which proved that the design was reasonable and in accordance with the code.
