摘要
温度效应已被纳入桥梁设计中,但在桥梁建设和运营中仍有温度裂缝出现,而这些温度裂缝大多由横向温度应力造成,因此横向温度应力在温度裂缝防治中逐渐占据重要地位。以横向温度应力的理论为基础,通过改变箱梁截面参数来分析其对横向温度应力的影响,为横向温度应力分析和桥梁结构的设计、施工及维护提供参考。
Although temperature effect of length direction has been considered in the bridge design, there are many temperature cracks in the process of construction or application, and most of those cracks are caused by temperature stress of cross direction, therefore temperature stress of cross direction gradually placed an important position. According to the theory of cross direction temperature stress, this paper analyses the stress by changing the size of section of box girder, its result could provide reference for the similar practice.
