Abstract:The transient temperature field and thermal creep surrounding concrete are analyzed with a three-dimensional FEM model that simulates the construction process of spiral case, based on program development of ABAQUS. The effect of hydration and cooling pipes on temperature is studied. The comparison of temperature difference in schemes is performed, and then the reasonable construction scheme has been defined. The distribution of thermal creep stress with construction is given. It is concluded that the control measures is effective to temperature crack prevention.
