桥梁承台大体积混凝土结构在施工中容易出现裂缝的温度裂缝问题。本文针对在建的桥梁项目,对混凝土内部温度应力情况的进行了分析,通过采取温控措施,确定合理的配合比以降低水泥水化热,加冷却循环水管等措施,来降低混凝土的内部温升,减少表层与中心温差,从而尽可能的避免在混凝土表面和内部产生温度裂缝。 Bridge Cradle, Mass Concrete Structure, Cracks, Temperature Crack, Crack in Construction In this paper, the bridge under construction project, the internal temperature stress analysis of the concrete, through the temperature control measures to determine the reasonable mix to reduce the cement hydration heat, cooling and cooling water pipes and other measures to reduce the internal temperature of concrete Rise, reduce the temperature difference between the surface and the center, so as to avoid the occurrence of temperature cracks in the concrete surface and internal.
