大体积混凝土裂缝成因与预防控制措施应用研究——以华阳街道28街坊J1-3地块项目为例

Research on Causes of Mass Concrete Cracks and Application of Preventive Control Measures--Example of J1-3 Plot Project in Block 28 of Huayang Street

大体积混凝土裂缝控制是保证建筑主体质量的重中之重,一旦有裂缝产生,将对主体结构的耐久性、安全性产生重大影响,后期修复会增加建设成本。本文综合实际工程案例及建筑施工规范相关内容,分别从大体积砼的定义、裂缝产生的原因、防止裂缝形成的技术措施等方面,详细阐述大体积混凝土控制裂缝形成的措施。

The control of mass concrete cracks is the top priority to ensure the quality of the main body of the building.Once cracks occur,it will have a significant impact on the durability and safety of the main structure,and the subsequent repair will increase the construction cost.Based on practical project cases and relevant content of building construction specifications,this article elaborates the measures to control mass concrete crack formation from the aspects of the definition of mass concrete,the causes of cracks,and the technical measures to prevent crack formation.
