地下室外墙混凝土裂缝机理分析及控制措施

针对地下室外侧墙施工中引起混凝土变形进行了分析。在初步探讨了底板大体积混凝土在施工中裂缝的成因后，进一步分析了地下室外墙这种特殊的大面积混凝土裂缝成因。针对裂缝成因分析结果，从混凝土的材料、外界环境、约束条件三方面对地下室外墙的裂缝进行了控制研究。

Mechanism Analysis and Control Measures of Basement Concrete Wall Cracks

The outer wall of cast-in-place basement causes the concrete out of shape to be analyzed while constructing at first. The paper has probed into board concrete after the origin cause of formation of the crack in constructing of large volume in the bottom tentatively. The paper has analyzed the concrete crack origin cause of formation of special large area of outer wall of the basement further. Analysis result, this text form designing, the materials of concrete to crack origin cause of formation, external environments, retrain terms face basement is controlled and studied by the cracks of outerwall all sides.
