严寒地区混凝土内部温度场变化规律的反演分析

摘要

Based on the analysis of internal temperature change mechanism of heat-preservation concrete during constr uction and operation periods in the cold area, this paper puts forward the mathematical model of temperature change of heat-preservation concrete. According to internal temperature monitoring data of concrete in cold area, this paper deeply discusses and studies on the change law of internal concrete temperature change with the time goes in different depths. Then it sums up how to use limited temperature observation data and how to set and optimize the mathematical model to reverse the internal temperature change law of concrete.%通过对严寒地区保温混凝土施工期到运行期内部温度变化机理进行分析,提出了反演保温混凝土温度变化的数学模型.结合严寒地区混凝土内部温度的长期监测资料,对混凝土内部不同深度温度随时间的变化规律进行了深入探讨和研究,总结了如何利用有限的温度观测资料,通过建立和优化数学模型,反演保温混凝土内部温度场的时空变化规律.
