研究了日照温度梯度荷载作用下混凝土箱梁的横向温度应力的计算方法．基于热弹性理论和应变阻止法基本理论并考虑纵横向应力之间的耦合，提出一种新的横向温度应力的计算方法．通过与中国公路桥涵设计规范即采用结构力学不考虑应力耦合的计算方法进行对比，证明这两种不同计算方法得出的结果存在明显差别．

This paper mainly studies the calculation of transverse temperature stress for concrete box girder under the sunshine temperature load. Based on thermo-elastic theory, and strain prevent theory and con sidering longitudinal and transversal stress coupling, a new calculation method for transverse temperature stress is proposed. The comparison with the Chinese highway bridge design code which uses structural me chanics and does not considers stress coupling proves that there are significant differences in the results of two different calculation methods.
