摘　　要： 混凝土连续梁桥的设计过程中,除了考虑恒载和汽车活载之外,温度变化对结构的影响也不可忽视,在某些情况下温度变化引起的效应甚至超过了汽车活载引起的效应。温度差效应包括整体升(降)温效应和局部升(降)温效应,这2种效应对连续梁的影响不同。通过采用有限元方法对2个具体工程实例进行研究,计算分析温度整体效应和局部效应的影响,总结出温度差效应的规律。 Thus continuous was used more widely, When designed, not only dead load and live load must be considered, but also temperature effect on structure must be considered too. In some case, that is even more than live load＇s effect. The temperature effect includes whole temperature effect and local temperature effect, which different from each other. In this paper, by finite element method, two projects are studied, and the whole temperature effect and local temperature effect are calculated. Used finite element method to study two specific projects, calculate and analyze the whole temperature effect and local temperature effect, sum up the law of temperature effect.
