大体积混凝土温控措施研究

Study on Temperature Control Measures of Mass Concrete

混凝土坝的裂缝是一个水利工程中普遍存在的工程问题,它会使建筑材料变性,丧失原有的承载力和使用价值,更有甚者会导致溃坝,威胁国家利益和上下游居民的生命财产安全,影响社会的安定团结。本文针对混凝土由温度引起的裂缝问题,分析了温度裂缝的分类、产生原因、控制手段,总结了各种温度控制措施,以保证建筑物和构件安全、稳定地工作。

Crack of concrete dam is a common problem in hydraulic engineering, it can change material＇s characteristics, make them to lose their original bearing capacity and use value, furthermore, it can cause dam-break, threatening national interests and resident＇s life and property, as well as affecting society＇s stability and solidarity. Aiming at crack problems caused by tem- perature, crack type, causes and control measures are analysed, and some temperature control measures are summarized, so as to guarantee the safety and stability of buildings and components.
