The sealing concrete of arch bridge will be constructed after swivel construction of it finished. The concrete has such characteristics like huge size, smaller heat radiating area and more complex boundary constraint. According to the cracking situation of this type bridges in recent years, the paper established hydration heat simulation model of it using MIDAS2010 program and numerical analyzed for the model. The hydration heat constant coefficients and placing temperature of the concrete hydration heat effect have been analyzed by simulation parameters base on that. And the results showed that it is an important reason causing the cracking of the concrete.
