摘要
在某铁路既有框构接长项目中,使用了斜交无桥台刚构连续梁结构,结构跨度为8.46 m+16,92m+8,46m对此桥的设计过程和受力特点进行了分析、研究。采用Midas和RBCAD软件分别建立上部结构和桩基础的计算模型,介绍了本桥桩基础设计的方案比较过程,同时进行了上部结构的内力分析。
In a railway frame extending project,the oblique crossing no-abutment rigid frame bridge is used.The span is 8.46 ＋ 16.92 ＋ 8.46 m.This article presents design and analysis of stress characteristics of this bridge.Computational models of the superstructure and the sub-structure by using the Midas and RBCAD,respectively.The paper also introduces the scheme comparison process of pile foundation design.The internal force and displacement under loading and eigenvalues were described.
