摘要
大连小窑湾5-2号路跨翔凤河桥为(30.5+45+30.5)m的3跨钢管连续桁架桥,介绍了该桥的总体设计,利用空间有限元程序Midas软件对其进行了分析,作为设计的指导和依据。在国内首次采用空间钢管桁架建造公路桥,为此类结构在桥梁方面的进一步应用积累了一定的经验。
The No.5-2 Xiangfenghe River Bridge in Xiaoyaowan of Dalian City is a 3-span（30.5 m ＋45 m ＋30.5 m） steel-pipe truss bridge. This paper introduces the general design of the bridge,makes analysis on it by using spatial finite element program,Midassoftware,being as the guidance and basis of the design. It is the first time in China to adopt spatial steel-pipe truss to construct the highway bridge and accumulate certain experiences for the application of such structure in bridge construction.
