大体积混凝土温度控制与现场监测

Controlling and in-site monitoring temperature in mass concrete

本文针对大体积混凝土结构的温度应力和温度裂缝问题,阐述了施工过程中温度控制和温度监测的必要性,介绍了工程中几种常用温度控制措施,并以某高层建筑物基础底板为实例,对大体积混凝土施工全过程进行实时温度监测,监测结果将为混凝土结构早期裂缝控制和耐久性研究提供有益参考。

To prevent temperature cracking in mass concrete,the significance of temperature control and temperature monitoring during the construction period is discussed.Several technical measures and methods about temperature control used in engineering are introduced.As an example,real-time temperature monitoring of concrete baseplate of a high building is carried out in the entire construction period.The monitoring results will give valuable references to the research on concrete early-age cracking control and durability.
