水混凝土构件产生裂缝的原因及预防措施

砼裂缝的产生既有内因又与外部条件有关，非常复杂；既有单一因素，又有综合因素。因此对某一种裂缝的产生不应孤立地去看，应进行综合分析。另外，其也并不是一个纯技术问题，在很大程度上是施工管理问题、责任心问题。因此，只要严格控制施工质量，严格执行施工技术操作规程，这些裂缝是可以预防和避免的。

Causes Creating Cracks of Cement Concrete Component and Preventive Measures

The producing of cement concrete crack relates to intrinsic factors and external agencies. The process is very complex with single factors and synthetical factors. Therefore some kinds of crack should not be considered with single cause, but be analyzed synthetically. Otherwise it is not only a simple technical problem, but a problem concerning construction management and responsibility. As long as the construction quality is controlled strictly and the technical operational regulations of construction are implemented strictly, the cracks will be prevented and avoided.
