| Abstract: | For the hydration heat generated by the massive concrete during the construction of the pier＇s base, the methods and operation processes of temperature control are presented in this article, using the finite element program MIDAS analyze the massive concrete temperature field of the hydration heat during the construction of the base. Besides, temperature control program for the construction of massive concrete, simulation of the calculation result and controlling calculation following the process of the construction compared with the data of temperature monitoring are introduced. The result of analysis and calculation could be a reference for the similar construction. |
