控制地下室外墙混凝土收缩裂缝的技术措施

Technical measures of controlling the concrete shrinkage crack in the basement exterior wall

针对目前在地下室外墙出现混凝土收缩裂缝可能性较大的现状,从裂缝产生的原理出发,结合实际工程,从混凝土材料选择、混凝土试验、设计及施工过程控制等方面,提出了相应有效的技术措施,取得了可喜的成果。

According to the present situation of the high possibility of the concrete shrinkage crack in the basement exterior wall, the author puts forward the effective technical measures from the selection of the concrete material, the concrete test, the design and the construction process control combined with the practical engineering based on the principle of the crake, which has notable achievement.
