摘　　要：桥梁的混凝土构件体积大,容易产生温度裂缝。鉴于此,论文总结了桥梁混凝土温度裂缝的分类方法,从原材料、约束条件、施工工艺等方面分析了桥梁温度裂缝的产生原因。以某高速公路连续梁桥的承台为研究对象,提出了合理选择原材料、降低混凝土入模温度、设置冷凝管等措施来控制混凝土温度裂缝。The concrete members of the bridge are large and easy to produce temperature cracks.In view of this,this paper summarizes the classification method of bridge concrete temperature crack,and analyzes the causes of bridge temperature crack from the aspects of raw materials,constraint conditions and construction technology.With the cap of a highway continuous beam bridge as the research object,the reasonable selection of raw materials,reducing the concrete mold temperature,setting condensation pipe and other measures to put forward control the concrete temperature crack.
