摘要
本文根据工程实际情况,对混凝土裂缝的特征和主要原因进行了较全面的分析,针对地下室外墙易产生裂缝提出了预防措施和补救措施:加强优化设计,增强混凝土的抗裂能力,减少约束;组织合理施工和养护,减少混凝土温差和收缩,发现裂缝后,根据裂缝特征进行有效修补,从而克服混凝土开裂的质量通病。
Based on practical engineering situation,the characteristics of concrete cracks and the main reasons were more comprehensively analyzed.Easy to produce cracks for the basement wall,This paper puts forward principal preventive measures and remedial measures：Strengthening the optimal design to reinforce concrete cracking and reduce constraints;Organization of reasonable construction and maintenance to reduce temperature and shrinkage of concrete;and based on the characteristics of crack,effective remediation is adopted,thus to overcome quality defects of concrete.
