A three2dimensional finite element model is established,based on adiabatic temperature2rise experiment and the hydration heat of concrete effected by temperature, with which the temperature field of a mass concrete mock2up in 60 d is calculated and compared with data measured on site. The results show that the temperature rise inside the concrete is about 40 ℃, which is achieved between 5 and 7 d. The difference of temperatures between any two points is less than 25 ℃. The maximum of temperature gradients in the vertical direction is on both the top and bottom surfaces, which is attained at the beginning of cooling stage after the temperature rise.
