In order to explore the insulation measures of large-volume concrete during summer and winter pouring, based on a raft foundation large-volume concrete construction project, the influence of temperature control measures (external insulation material and concrete mold temperature) on the temperature field of large-volume concrete in summer and winter is explored by establishing a refined finite element model. The results show that: 1) The increase of the ambient temperature during pouring will increase the heat release of the concrete and prolong the heat release time, in summer, 3 cm thick extruded polystyrene board is used for insulation, and the peak temperature and required time are 66.8 ℃ and 114.7 h when the concrete mold temperature is 25 ℃. 2) Under the ambient temperature of the two seasons, the variation between the external thermal insulation performance and the inner surface temperature is decreased linearly, and the relationship with the core temperature is increased linearly. 3) Different insulation measures will delay the occurrence time of core temperature, and the better the insulation performance, the smaller the temperature gradient. 4) With the increase of mold temperature, the core temperature of concrete increases, and the occurrence time is advanced. The results can provide references for the construction of large-volume concrete for the same type of raft foundation.
