摘要
针对严寒地区的气候特征,文章对现浇钢筋混凝土结构裂缝的形成原因进行分析,从原材料、设计、施工等方面研究控制裂缝措施,再结合实际工程案例,对严寒地区现浇钢筋混凝土结构出现裂缝现象的具体原因进行剖析,采取有效的裂缝修补措施,满足规范及使用要求。
In view of the climatic characteristics of cold regions,this paper analyzes the causes of the formation of cracks in cast-in-place reinforced concrete structures,and studies the crack control measures from the aspects of raw materials,design,construction,etc.,combined with actual engineering cases,analyzes the specific causes of cracks in cast-in-place reinforced concrete structures in cold regions,and takes effective crack repair measures to meet the specifications and application requirements.
