摘　　要：大体积混凝土作为建筑工程中常用的结构材料,如何有效控制大体积混凝土裂缝,已成为建筑工程施工中的一个重要课题。本文以实际工程为研究对象,从温度裂缝产生机理入手,分析了影响大体积混凝土裂缝的主要原因,有针对性地整理论述了大体积混凝土温控措施。结合工程实际论述了优化配合比、冷凝水管以及施工养护精细化管理等多元化一体措施对于控制大体积混凝土的作用。研究结果表明,本工程所采取的温控措施很好地控制了混凝土内外温差及应力,确保了大体积混凝土的浇筑质量,该方法可为后续相关工作的开展提供借鉴。Mass concrete as a commonly used structural material in construction projects,how to effectively con-trol the cracks of mass concrete has become an important topic in the construction of building projects.This paper takes the actual project as the research object,starts from the mechanism of temperature cracks,analyses the main reasons affecting the cracks of large volume concrete,and discusses the temperature control measures of large volume concrete in a targeted manner.Combined with the actual project discusses the optimisation of mixing ratios,condensate pipe and construction and maintenance of fine management and other measures for the control of mass concrete.The results show that the temperature control measures used in this project is very good control of the temperature difference between inside and outside of the concrete and stress,to ensure the quality of mass concrete pouring,the method can be said to be followed by the development of the relevant work to provide a ref-erence.
