大体积混凝土温度裂缝的成因分析与防治措施

Cause Analysis and Prevention Measures of Mass Concrete Temperature Cracks

在大体积混凝土运用范围不断拓展的背景下,如何准确辨识其温度裂缝成因,强化裂缝防治措施的针对性,成为大体积混凝土施工中的关键课题之一。基于此,本文首先介绍了大体积混凝土裂缝的类型,分析了大体积混凝土温度裂缝的成因,并结合相关施工管理经验,分别从建立完善大体积混凝土施工工艺控制体系等多个角度与方面,探讨了大体积混凝土温度裂缝的防治措施,阐述了个人对此的几点认识。

Under the background of the continuous expansion of the application range of mass concrete,how to accurately identify the causes of temperature cracks and strengthen the pertinence of crack prevention measures has become one of the key issues in the construction of mass concrete.Based on this,this article first introduces the types of mass concrete cracks,analyzes the causes of mass concrete temperature cracks,and combines relevant construction management experience to discuss the prevention and control measures of temperature cracks in mass concrete from multiple perspectives and aspects of the establishment and improvement of mass concrete construction process control system,and expound the author’s understandings about this issue.
