Thermal Stress Numerical Simulation on Concrete Hydration Heat of Giant Floor in Deep Foundation Pit

Article Preview

Abstract:

The finite element analysis software, during the pouring of concrete for the temperature field and stress field in a numerical simulation analysis. Analysis showed that the concrete core temperature changes greater maximum thermal stress in mass concrete bottom and around the site and soil transfer, far less than the concrete tensile stress, the temperature will not crack.
