Simulation of Temperature Field on Massive Concrete

摘要

Based on the geological conditions of cut and cover tunnel of the South to North Water Transfer Project, lining temperature field for crack control is simulated by finite element software-ANSYS. Through simulation of hydration heat effects, large temperature difference areas can be identified quantitatively, thermal insulation and sprinkler maintenance can be carried on during the initial setting. Cracks can be controlled well by pouring concrete in different section, mixing amount of fly ash and controlling mold temperature reasonable. Thus, model can be optimized continuously, optimal solution will to be established to provide better reference for selecting the temperature control program of massive concrete.
