| Abstract: | The main factors, such as limiting extended value, elastic module and thermal deformation of the influence on crack resistance of mass concrete have been analyzed in this paper. We present the criterion of crack resistance of the mass concrete and use it to evaluate the crack resistance of the mass concrete with experiments. After analyzing the reasons responding for the situations, we get an agreement result. The criterion can provide us reliable of valid experimental basis on crack resistance design and stage curing of mass concrete. |
