Aiming at discussing the time-varying characteristics of massive concrete in the construction period,we use Genetic Algorithm to inverse the parameters and achieves optimal solutions of adiabatic temperature rise,which is the major impact on the adiabatic temperature rise of mass concrete,i.e.,the unit mass of cement the final heat Q0 and the real constant n.Based on the actual measurement of environmental parameters and inversion results,we establish the three-dimensional finite element heat-transfer model of ANSYS .Comparing the results of numerical simulation and measured data,we know that the temperature field of hydration heat aging model can accurately simulate the engineering practice more.The results of time-varying temperature field and temperature variation show that the mass concrete layered construction peak temperature is related to the thick and pouring interval,and not necessarily occurs in the center of each layer;The development of temperature peak duration curves is similar to the temperature difference duration curve,thus it may serve as reference for the node time of temperature controlling.
