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 。
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.
