摘　　要：混凝土箱梁受不均匀温差作用会产生较大的温度应力,故通过实例,分析混凝土预制小箱梁各施工阶段的日照温差作用,研究其温度场分布规律,并比较其与现行规范的差异,其结果可为同类工程的施工提供参考。Being subject to the asymmetry temperature function, the concrete casket beam would produce bigger temperature response. Analysis the sunshine temperature function of the concrete casket beam＇s each stage construction and studying the distribute regulation of its temperature field by example. Finally, the difference of comparing it with the current norm is got, and the result of analysis and studying it can give reference for similar engineering construction.
