| Abstract: | According to the in-situ measurement of temperature and weather,based on the optimized genetic algorithm and the strict numerical iterative procedure of cooling-pipe,back analysis of characteristic parameters is carried out for the constructional C25 concrete of the pier.The results of back analysis show that the computational results have a good agreement with the measured values and the parameters are reliable.It will provide important reference to temperature control simulation,so as to provide an effective method for solving the problem of temperature crack. |
