摘要
地下室外墙混凝土结构出现裂缝的主要原因是温度效应,文中以某大型综合建筑工程为例,分析了有限元模型的建立,从板的变化、侧墙的变化、地基水平阻力的变化、混凝土结构裂缝的分布情况四方面对其温度效应进行详细分析,并以原料、设计和施工为基础提出了具体的裂缝控制措施,以期为类似项目提供参考。
The main cause of cracks in the concrete structure of the basement exterior wall is the temperature effect.Taking a large comprehensive construction project as an example,this article analyzes the establishment of a finite element model,and analyzes its temperature effect in detail from four aspects:changes in the slab,changes in the side wall,changes in the horizontal resistance of the foundation,and distribution of cracks in the concrete structure.Based on raw materials,design,and construction,specific crack control measures are proposed,To provide references for similar projects.
