在工程项目施工中，混凝土开裂是一种常见的技术问题。如果不能合理地采取一些正确的施工方法和有效的控制措施，很容易造成混凝土的裂缝，影响结构的使用，甚至造成结构的破坏。因此，混凝土的裂缝控制问题非常重要。本文将分析混凝土裂缝产生的原因、机理，并提出具体的防裂缝措施。%During the construction of the project, concrete cr-acking is a common technical problem. If it is not reasonable to take some construction method is correct and effective cont-rol measures, it is easy to cause the crack of the concrete struc-ture, use, or even cause structure damage. Therefore, control of cracking in concrete is especial y important. The paper analyz-es the mechanism and causes of cracks in concrete, and puts f-orward the concrete crack prevention measures.
