钢筋混凝土盒子结构裂缝的分析及控制

The analysis and control about cracks of the reinforcement concrete box module

钢筋混凝土盒子结构是一种多约束的空间薄壁结构。通过对该结构体系从结构特点到生产、施工过程及施工前后外界环境的影响等方面进行分析 ,找出裂缝成因 ,提出相应的控制措施 ,在生产、施工中收到了良好的效果。实践证明 ,只要遵守施工程序 ,并根据裂缝产生特点 ,采取相应措施 ,裂缝就可以大大减少。

The reinforcement concrete box module is a kind of space thin-walled structure with many constraints. From the views of the structure characteristic, production and construction process, influence of outside environment before or after construction the paper analyzes the structures system. The reasons for cracks are found. And some agreeable control measures are proposed. Good effect is attained in the process of production and construction. The practice proves that the cracks will be reduced enormously when the construction process is abided by and relevant measures are adopted.
