地下墙体竖向裂缝成因分析及预防措施

UNDERGROUND WALL VERTICAL CRACK ORIGIN ANALYSIS AND PREVENTION MEASURES

在工程结构设计中,地下外墙特点是墙体厚、跨度长,施工过程中竖向裂缝比较常见,成为一种混凝土的质量通病。结合工程实例,针对地下墙体结构的竖向裂缝的形成综合因素进行了较为细致的分析,根据分析结果做出了部分调整,细化了施工环节的操作,达到了控制同样类型裂缝的再次产生。

In the design of engineering structures,underground wall features long span and thick wall,in the process of the construction vertical cracks are relatively common,become a kind of concrete quality common fault.Combined with the engineering example,it was analyzed the comprehensive factors of forming the vertical cracks on the underground wall structure,according to the results of the analysis some adjustment refinement of the operation was made to avoid to same types of cracks.
