钢筋混凝土结构是一种耐久性较好的结构体系,但是由于混凝土的均质性较差,抗拉强度较低,又有膨胀收缩、徐变等特性,加之施工过程控制不严、设计考虑不周、使用不当等原因,致使混凝土结构出现不同程度的裂缝,给结构造成一定的损伤。文中对混凝土裂缝成因及控制措施加以分析总结,以便在施工过程中更好的对裂缝加以认识、控制和预防。
Reinforced concrete structure is a kind of better durable structure system, but due to the poor homogeneity of concrete, low tensile strength, and the characteristics of expansion, shrinkage and creep, combined with the lax control of the construction process, the design considerations Weeks, improper use and other reasons, resulting in different degrees of cracks in the concrete structure, to the structure caused some damage. In this paper, the causes of concrete cracks and control measures to be analyzed and summarized in order to better understand the cracks in the construction process, control and prevention.
