Abstract：Focusing onthe problem of heat hydration of large-volume concrete，a finiteelement temperature field analysis method was proposed.The heat conduction theory was analyzed in depth，and the temperature field changes of large-volume concrete in the hydration process were analyzed by finite element software，and compared with the measured results.The results showed that the temperature field variation of the simulated temperature fieldand rain measured bythe finiteelement analysiswasconsistent，which indicates that the temperature field changeof largevolume concretecan berevealed through finite elementanalysis.Through this method，the temperature fieldof largevolume concrete can be controlled to prevent early cracking.

Keywords：hydration heat;heat transfer theory;large volume concrete;temperature field;finite element analysis
