摘要: 参照4个国家5种规范关于温度梯度的不同规定,对3种不同桥型的砼箱梁的温变横向应力作了计算和比较,并对温度敏感性作了分析,结论表明温度效应是桥面开裂的重要原因之一

关键词: 砼箱梁, 温度, 横向应力, 敏感度

Abstract: Refering to different rules on temperature gradient in five specifications,the paper calculates transverse stresses of temperature change for concrete box-girders of three bridge types,as well as makes an analysis of temperature sensitivity.The results indicate that temperature effect is one of important reasons causing the bridge deck crack.

Key words: concrete box-girder, temperature, transverse stress, sensitivity
