In this paper, the computer simulation temperature field distribution of Jingshan rock fill concrete gravity dam is studied, and computer simulation analysis is carried out based on two schemes: no temperature control measures and simple temperature control measures. The computer simulation results show that the temperature of the dam body begins to rise with the increase of air temperature. With the increase of elevation, the dam body becomes thinner, and the computer simulation temperature inside the dam body changes periodically with the air temperature. Under the condition of simple temperature control measures, the distribution law of the dam body computer simulation temperature field is basically consistent with that without temperature control measures, and the computer simulation overall temperature value decreases slightly, but it is still unable to ensure that the dam concrete will not crack. It is necessary to further study the implementation plan of the dam body joint division and temperature control measures.
