现浇混凝土结构由于多方面的原因往往会出现一些裂缝,是具有较普遍性的质量问题。混凝土结构构件出现裂缝,不但影响外观,而且有可能影响构件的刚性和结构的整体性,当裂缝宽度超过一定限度,有时会造成钢筋锈蚀,影响结构构件的耐久性,因此鉴别裂缝、分析裂缝、控制裂缝的产生和发展,并对裂缝的产生进行有效的防治,对保证混凝土结构的整体性及正常使用具有重要的意义
Cast-in-place concrete structures tend to show some cracks due to various reasons, which is a more general quality problem. Cracks in concrete structures not only affect the appearance, but also affect the rigidity of components and the integrity of structures. When the width of cracks exceeds a certain limit, steel bars may be corroded and the durability of structural members may be affected. Therefore, cracks are identified, cracks are analyzed, Controlling the generation and development of cracks, and effective prevention and control of cracks, is of great significance to ensure the integrity and normal use of concrete structures
