| Abstract: | 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. |
