| Abstract: | An analysis of the big bulk the concrete construction period temperature coure with the random adiabatic temperature rise,atmospheric heat exchange coefficient,thermal conductivity atmospheric temperature is made by the Neumann expansions Monte-Carlo stochastic finite element method.According to the result,the main factors that impact the maximum temperature during the prcess of pouring are adiabatic temperature rise and atmospheric temperature. |
