摘要
为提高连续梁桥设计水平,文章首先从荷载作用和结构两方面分析了连续梁桥的倾覆破坏特征,随后分析了连续梁桥的倾覆破坏机理,并以某高速公路大桥项目为研究对象,利用Midas/Civil软件建立若干个有限元模型,采用参数控制变量法,研究支撑方式、曲率半径、桥面宽度等因素对主梁抗倾覆稳定性系数的影响,以期为桥梁工程设计与施工提供参考。
In order to improve the design level of continuous beam bridges,this paper first analyzes the overturning failure characteristics of continuous beam bridges from two aspects of load action and structure,and then analyzes the overturning failure mechanism of continuous beam bridges.Taking an expressway bridge project as the research object,several finite element models are established by using Midas/Civil software,and the influence of support mode,curvature radius,bridge deck width and other factors on the anti-overturning stability coefficient of the main beam is studied by using parameter control variable method,so as to provide reference for bridge engineering design and construction.
