Chemical reaction rate is used to interpret the influence of temperature on adiabatic temperature rise of concrete,equivalent time-based nonlinear heat conduction equation is solved,and simulation calculation is done for temperature field and creep stress field of a certain aqueduct in the construction of the South-to-North Water Diversion Project.Study shows that calculation results obtained from equivalent time-based concrete adiabatic temperature rise theory and traditional theory for concrete placement in the summer and in the winter are different.
