摘　　要：大体积混凝土施工过程中由于水化热作用很容易产生早期裂缝,结合包头黄河大桥主墩承台施工,对其温度裂缝的成因、影响因素和控制措施进行了探讨,取得了较好效果,可为类似工程提供参考。Early crack is easily produced in the massive volume concrete construction due to the effect of hydration heat. This paper, referring to the pile cap construction of Baotou Yellow River Bridge, discusses the causes and influence factors of temperature cracks and control measures. Positive result is acquired and the methods introduced in this paper may provide references for similar works in the future.

关 键 词：承台 大体积混凝土 施工裂缝控制
