某国道大跨槽型梁受力分析与施工技术研究

On stressed analysis of large-span u-shaped girder on some national road and its construction technique

以某国道中大跨桥的槽型梁贝雷支架设计与施工为工程背景,介绍了该支撑体系的布置方法,并建立了有限元模型,对支架系统的强度、刚度和变形性进行分析研究,从基础工程、钢管立柱、分配梁、贝雷片施工等方面,阐述了具体的施工技术,有效保证了工程的质量。

Taking the bailey truss support design and construction at the u-shaped girder along some national road as the engineering background,the paper introduces the layout methods for the support system,establishes its finite element model,analyzes the stiffness,strength,and deformation of the support system,and illustrates its construction technique from the foundation project,steel-pipe post,distributive girder,and beam distribution,so as to ensure the engineering quality.
