摘要:本文主要阐述建筑主体结构裂缝的成因及预防措施.明确混凝土裂缝的危害严重程度及混凝土裂缝的根本成因.从混凝土自身质量问题,而产生的碱骨料反应引发裂缝、季节性施工及自身水化热的温度应力变化产生裂缝。地基不均匀沉降、混凝土早期强度不足已承载自身荷载或施工荷载而产生裂缝。以及施工过程中指令信息或管理不当、未按照设计图纸要求或相应规范及施工方案进行施工等,几方面分析裂缝产生的原因。
Abstract: This article mainly elaborates on the causes and preventive measures of cracks in the main structure of buildings. Clarify theseverity of the harm caused by concrele cracks and the fundamental causes of concrele cracks.Cracks are caused by the alkali aggregaltereaction caused by the quality issues of concrelte iself, seasonal construction, and temperature stress changes caused by its own hydrationheat. Uneven settlement of the foundation, insufficient early strength of the concrele, and the occurrence of cracks due to bearing its ownload or construction load. And analyze the rasons for cracks from several aspects, such as improper instruction information or managementduring the constuction process failure to follow the design drawings or corespondling specifications and construction plans for construction.
