摘要
在城市混凝土曲线桥梁结构设计中,温度因素是结构设计需要重点考虑的一项因素。文章以江西省九江市某实际工程为例,运用有限元模型分析和数值模拟的方法,在分析系统升降温对曲线箱梁桥横向稳定性具体影响的基础上,计算了不同升降温情况下曲线梁桥主梁的径向位移与扭转角,分析了系统温差对城市混凝土曲线梁桥横向稳定性的影响,以供参考。
In the design of urban concrete curved bridge structure,temperature factor is a key factor to be considered in structural design.Taking a practical project in Jiujiang City,Jiangxi Province as an example,this paper uses finite element model analysis and numerical simulation methods to analyze the specific influence of system temperature rise and fall on the lateral stability of curved box beam bridges.Based on this,the radial displacement and torsion angle of the main beam of curved beam bridge under different temperature rise and fall conditions are calculated,and the influence of system temperature difference on the lateral stability of urban concrete curved beam bridges is analyzed for reference.
