摘要: 活性粉煤灰混凝土(RPC),是一种新型活性高性能材料,在未来桥梁工程中将有良好的经济和使用价值。利用Midas软件建模分析在西平铁路线莫谷河2号大桥中粉煤灰混凝土的设计应用,比较了RPC混凝土空心薄壁墩和传统桥墩在强度、刚度、施工性能方面的差别,系统地分析各种桥墩结构力学数据。探讨了RPC混凝土空心薄壁墩在铁路桥梁应用中在刚度方面的问题,提出了合理的设计方案和技术措施。

关键词: 活性粉煤灰混凝土, 空心薄壁墩, 刚度

Abstract: Active fly ash concrete(RPC), is a new kind of activity in the future, high\|performance materials bridge engineering, there will be good economic and use value. This study uses “Midas” software modeling analysis in Xiping railway bridge in the omo valley poses the design and application of coal ash concrete compared the RPC concrete hollow thin\|wall piers and traditional pier stiffness, strength, especially in the construction, a systematic analysis of structural mechanics data pier. Discusses the RPC concrete hollow thin-wall piers in railway bridge in the application of the stiffness, puts forward the reasonable design scheme and technical measures.  

Key words: active fly ash concrete, hollow thin\, wall piers, stiffness
