承台大体积混凝土水化热温度监测技术

Monitoring technology of hydration heat temperature of mass concrete on platform

以某承台大体积混凝土施工为例,为控制水化热现象,通过采集现场温度监测数据,探究水化热过程中温度变化规律,绘制温度应力时程曲线,并运用粘弹性方程对温度应力进行分析,进而提出相应的温控措施。

Taking the mass concrete construction of a bearing platform as an example, in order to control the phenomenon of hydration heat, through the collection of on-site temperature monitoring data, this paper explores the law of temperature change in the process of hydration heat, draws the time history curve of temperature stress, analyzes the temperature stress by using the viscoelastic equation, and puts forward corresponding temperature control measures.
