混凝土裂缝的预防和处理

Precautions and treatments

混凝土在现代工程建设中占有重要的地位。在众多的工程质量问题中混凝土裂缝现象则更为突出,因此必须十分重视混凝土裂缝的成因与预防。在工程实际中除了荷载作用造成裂缝外更多的是混凝土收缩;温度应力变形和不均匀沉降等导致开裂。我们必须对其进行有效地控制,特别是避免有害裂缝的产生。本文对混凝土工程中常见的一些裂缝问题进行了探讨;分析,并根据具体情况提出了一些预防,处理措施。

Concrete plays an important role in modem engineering. Among numerous engineering quality problems, concrete cracks are typical, and therefore, the reason for and the precaution of the formation of concrete cracks should be given much attention. In practice, Reasons for concrete cracks are concrete contraction, temperature stress deformation and unequal settlement, besides load effect. We must control the aforesaid problems effectively, and especially avoid the formation of destructive cracks. This paper analyzes some common cracks in concrete engineering and puts forward some measures for precaution and treatment.
