以中关村壹号A,D区重大工程为背景,为有效解决施工过程中大体积混凝土施工温度裂缝的技术难题,通过总结实际工程经验,提出并研发了一种以循环水为媒介的高效控制厚大基础混凝土温度裂缝的方法。采用现场温度监测的方法对基础底板混凝土进行了试验研究,并对基础底板混凝土内部温度场进行了系统分析,总结出了基于循环水控制基础混凝土施工裂缝的温度变化规律,为相关实际工程提供数据支持和参考。 Based on the major projects of Zhongguancun Area A and D, in order to effectively solve the technical problems of temperature cracks in the mass concrete construction during the construction process, this paper proposes and develops a kind of high-efficiency control thick medium Method for Temperature Cracking of Large Foundation Concrete. Based on the on-site temperature monitoring method, the foundation slab concrete was studied and the internal temperature field of foundation slab was systematically analyzed. The temperature variation rules of concrete construction cracks based on recirculating water control were summarized and the data were provided for relevant practical projects Support and reference.
