摘　　要：大体积混凝土因水泥水化热、外界温度、混凝土入模温度等多方面的综合因素产生裂缝,因影响程度的大小不同,产生裂缝的深度分为表面裂缝、深层裂缝和贯穿裂缝,文中通过对大体积混凝土温度裂缝产生的原因进行了分析,同时也通过查阅相关文献提出相应的建议,希望可以减少大体积混凝土温度裂缝的产生,为相关从业者提供参考。Mass concrete cracks due to various comprehensive factors such as cement hydration heat,external temperature,concrete mold temperature and other factors.Due to the different degree of influence,the depth of the cracks is divided into surface cracks,deep cracks and through cracks.This article Through analyzing the causes of temperature cracks in mass concrete,and at the same time by consulting related documents,corresponding suggestions are put forward,hoping to reduce the occurrence of temperature cracks in mass concrete,and provide references for related practitioners.

关 键 词：大体积混凝土 温度裂缝 水化热
