现浇混凝土板的裂缝分析与防治

在建筑结构中，随着商品混凝土的大量使用，混凝土楼面板出现裂缝的机率大大增加，并日益受到人们的关注。裂缝出现的原因复杂，既有温度变化、混凝土收缩、地基不均匀沉降等原因，也有设计、施工、材料和使用等方面的问题。本文根据工程实践经验，对现浇混凝土板的裂缝在设计、施工、材料等方面的成因进行了分析，并提出了相应的裂缝防治措施。

Cast-in-place Concrete Slab Cracks＇s Analysis and Prevention

In building structures, with a large quantity of use of commodity concrete, concrete floor cracks probability increases greatly, and people pay more attention to it. The causes of cracks is complex, it contains temperature changes, shrinkage of concrete, the uneven settle- ment of foundation and other reasons, there are design, construction, material and applying the likes. According to the engineering practice, this paper analyses the causes of the concrete slab crack in design, construction, material and other aspects, and puts forward the corresponding prevention measures for cracks.
