Abstract: The causes of the cracks in the beam and slab are the design, the foundation settlement, the deformation of the support system, the concrete shrinkage, the temperature difference, the material quality, the construction quality and so on. So in this paper, the formation of the crack was analyzed from three aspects, such as design, construction and other reasons, the prevention measures of cracks were also introduced. Finally the treatment effects by the epoxy resin adhesive sealing method and epoxy resin pressure grouting method were introduced to provide reference for the similar project.
