Field back analysis of temperature problems and construction feedback

A temperature calculating model and related parameters are obtained by back analysis of field measured data. The model and parameters obtained are used to predict the temperature and stress state of concrete by simulating calculation so as to guide the further construction, thus a temperature control and feedback mechanism is formed. The effectiveness of the model is verified by its application to the Huai'an underground culvert project. Furthermore, an exponential hyperbolic expression is proposed to describe the adiabatic temperature rise of concrete mixed with inhibiting agents. Practice shows that the formula can give accurate descripation of the characteristics of adiabatic temperature rise of the concrete.
