本文结合了国家和上海市有关技术标准,从裂缝的基本概念和国内外研究的现状入手,通过对混凝土结构材料的基本物理力学性能和混凝土结构因温度变形、收缩变形及地基的不均匀沉降等所产生的应力裂缝的角度分析和探讨了钢筋混凝土结构裂缝的成因。通过分析裂缝的种类和产生的原因,合理选择结构形式,并从设计、材料、施工等方面提出解决措施,从而有效地控制和减少混凝土结构裂缝的产生。 This paper combines the relevant national and Shanghai technical standards, starting from the basic concepts of cracks and the status quo at home and abroad, through the basic physical and mechanical properties of concrete structures and concrete structures due to temperature deformation, shrinkage deformation and uneven foundation settlement The stress cracks generated point of analysis and discussion of the causes of cracks in reinforced concrete structures. By analyzing the types of fractures and their causes, the structural forms are selected rationally and the solutions are given from the aspects of design, materials and construction so as to effectively control and reduce the cracks in concrete structures.
