化工建设中混凝土结构裂缝的原因及防治措施

The Causes and Prevention Measures of Cracks in Concrete Structures in Chemical Construction

混凝土结构(构件)裂缝在混凝土结构中是常见的,混凝土的正常使用状态本身就是带裂缝工作的状态。出现裂缝后,就要分析哪些裂缝是有害裂缝,哪些是无害裂缝,经分析后,才能针对不同的裂缝进行针对处理。结合工作实践,从常见的裂缝产生原因入手。在混凝土裂缝的防治及施工方面注意的问题等方面,作一探讨。

Crack is a common matter in the concrete structures （the components）. For itself, serviceability state of concrete structures is working with cracks. Once cracks found, analysis about which are harmful and which are harmless is necessary. Such analysis is targeted for proper treatments and measures to be taken to deal with specific cracks. This paper starts with the factors that result in the cracks, and with combination of normal construction practice, makes an analysis on measures how to prevent and control cracks in the concrete structures as well as the relevant problems in the design and construction process.
