Abstract
Taking the concrete pouring for a passenger station’s pile cap as the research background, the paper establishes a model of pile cap’s hydration heat, by using the finite element software MIDAS. The paper also studies the main parameters and the temperature field theory which affect the hydration heat. It indicates that the pipe cooling method can significantly reduce the temperature difference between the inside and the outside when pouring massive concretes, and it is an effective way to prevent the generation of cracks.
