The invention discloses a method for determining the casting temperature for finite element calculation according to casting-temperature measurement values. On the basis of the actually-measured casting temperature, the hydration-heat-releasing influence factor is removed, and according to finite element data, the ratio between the paving-layer average casting-temperature increment caused by the external environment temperature and the actually-measured casting-temperature increment from spreading vibrating ending and paving-layer casting ending is fit, factors such as the placing temperature, the ratio between the paving-layer average casting-temperature increment caused by the external environment temperature and the actually-measured casting-temperature increment of actually-measured points of a paving layer from concrete spreading vibrating ending to paving-layer casting ending and the paving-layer-average-temperature variable quantity caused by the external environment temperature are synthetically considered, and the sum of the paving-layer average-temperature increments caused by the concrete temperature when spreading vibrating is end and the external environment temperature serve as the casting temperature of finite element calculation. Compared with the method that the actually-measured casting temperature is directly used as the casting temperature of finite element calculation, the calculating result is more accurate, and the scientific accuracy of the tracking simulation analysis result is improved.
