摘　　要：以建筑项目为例,结合现场监测、检测以及仿真等手段分析钢筋混凝土框架结构楼板裂缝的产生机理,并提出了一定的针对性建议。结果表明:楼面板裂缝的产生机理是配筋率、温差以及楼板自身变形综合作用的结果;楼面自身变形比温差对楼面板力学响应的影响作用更加剧烈;裂缝主要出现在楼面板四角的位置以及外墙转角处,且均呈现45°斜向放射状分布。Taking a building project as an example,this paper analyzes the mechanism of floor cracks in reinforced concrete frame structures by means of on-site monitoring,detection and simulation,and puts forward some specific suggestions.The results show that the cracking mechanism of the floor panel is the result of reinforcement ratio,temperature difference and the deformation of the floor itself.The effect of floor deformation on the mechanical response of the floor panel is more severe than that of temperature difference.The cracks mainly appear in the four corners of the floor panel and the corner of the external wall,and all present a 45°oblique radial distribution.
