Reducing the length of concrete pouring blocks is one of the most important measures for temperature control and crack prevention of mass concrete, but there is little exploration of the specific relationship between the temperature drop and the length of concrete pouring blocks. In this paper, the finite element model of different length is established for the concrete block in the strong restraint area of the concrete dam. The maximum concrete base temperature difference that can be withstood by the pouring blocks of strong restraint zone with different lengths is obtained, which can provide a reference for the temperature control index during the concrete pouring process.
