Evolution rules on temperature field of mass concrete with high strength in freezing construction method environment
In order to research on the influencing factors and development laws of the temperature field of mass concrete with high strength in the construction environment of the freezing method,taking the mass concrete with high strength shaft line of a coal mine in western China as an example,numerical analysis software was used to study the influence of concrete strength grade,shaft thickness and ambient temperature on the concrete temperature field,and the temperature was monitored at the construction site.The results show that the numerical simulation results are consistent with the field monitoring results.The measured value is lower than the simulated temperature peak,and the time of occurrence is earlier.The thickness and strength grade of the shaft line concrete have a significant influence on the temperature field.
