| Abstract: | Taking the building of electric power dispatching for example,this paper discusses how to use finite element method to calculate temperature field during the construction process of massive concrete.Temperature sensors were embedded to monitor the variety of temperature field.The discrepancy between data from monitoring and data from calculating is small,which illustrates that we can effectively forecast the variety of temperature field and draw out temperature control scheme using finite element method to prevent temperature cracking. |
