摘要
箱梁桥是裸露在地表上的结构物,温度变化对结构内力的影响不可忽略,我国公路规范对温差的规定适合大部分地区,但对于昼夜温差变化极大的地区不太适合;运用有限元建模实例进行分析,结果表明采用新西兰温度模式并适当加大温差值是比较符合工程实际的。
Box girder bridge is exposed on the surface of the structure, the impact of temperature change on the structural forces can not be ignored, China＇s highway specifications required temperature difference is suitable for most parts of the provisions of China, But not suitable for the temperature great difference between day and night region;Examples of the use of finite element modeling analysis shows that the New Zealand temperature mode that appropriate to increase the temperature difference value is more in line with the actual engineering.
