摘　　要：本文着重探讨了某大坝施工期间的关键环节——温度控制。根据研究结果显示,在冬季的低温条件下,基础强约束区能够轻松满足温控标准。至于基础弱约束区,其达标时间跨度为11月至次年2月。至于非基础约束区,其符合温控标准的时间则进一步延长至11月至次年4月。至于其他月份,则需采取额外的温控措施。2019年11月至2020年4月上旬,工程团队成功完成了基础约束区的混凝土浇筑工作。随后,他们迅速转向非约束区的浇筑作业。为了确保每一环节的施工都符合标准,工程团队还进行了一系列科学的温度计算,从而确保混凝土浇筑的质量。这些措施不仅确保了施工的顺利进行,还大大提高了工作效率和经济效益。This article focuses on the key link during the construction of a dam-temperature control.According to research results,under low temperature conditions in winter,the basic strong constraint zone can easily meet temperature control standards.As for the basic weak constraint zone,its compliance time span is from November to February of the following year.As for the non basic constraint zone,its compliance with temperature control standards will be further extended from November to April of the following year.As for other months,additional temperature control measures need to be taken.From November 2019 to early April 2020,the engineering team successfully completed the concrete pouring work in the foundation constraint zone.Subsequently,they quickly turned to the pouring operation in the unconstrained zone.In order to ensure that every stage of construction meets the standards,the engineering team also conducted a series of scientific temperature calculations to ensure the quality of concrete pouring.These measures not only ensure the smooth progress of construction,but also greatly improve work efficiency and economic benefits.
