With the help of thermodynamic formulae,the thermodynamic parameters of activation [free energy of activation(ΔG≠),enthalpy of activation(ΔH≠) and entropy of activation(ΔS≠)] for the explosive decomposition reaction were calculated.

A new method for back analysis on thermal parameters of mass concrete needs;

Stochastic back analysis of thermal parameters, including coefficient of thermal conduction, coefficient of heat conduction as well as coefficient of superficial radiation of transient temperature field of mass concrete, is presented using the Bayesian parameter estimation theory.

Analysis method of thermal parameters feedback during construction period of RCC dam based on artificial neural network;

Based on the 3-D finite element method of concrete temperature simulation and the date measured in the field of Baoying pump station,used genetic algorithms in back analysis of the concrete thermal parameters for pump station,good result is achieved;then the feedback analysis in the whole field is done on the previous result and the constructing process.

In the simulation of concrete temperature field,the thermal parameters which are usually acquired by the experiment or the empirical equation may not always consistent with the actual situation.
