Concrete temperature parameters have an important meaning for concrete temperature control and crack prevention.This paper uses a differential algorithm to simulate the temperature field of concrete.Based on measured temperature data,this paper analyzes the error of the simulation calculation and establishes an inversion model based on measured data.Based on the specific characteristics of the inversion model,a GA algorithm is constructed.Through the calculation of the inverse model,the concrete temperature parameters that are more in line with the actual situation can be determined so as to provide a reference for the reasonable determination of concrete temperature parameters and subsequent temperature control calculations.
