The Combined Analysis Method of Concrete Thermal Parameters and Its Application

Concrete thermal parameters are of great importance to temperature field simulation calculation and temperature control forecasting of a concrete structure.The article uses the analysis and back analysis combined method to find out a global optical solution to the non-linear inversion problem based on the primary 3-dimentional temperature field simulation program,taking into account the genetic algorithm.The temperature values measured at a number of points enable the inversion of temperature conduction coefficient and adiabatic temperature rise and surface heat emission coefficients to be realized.Both practicability and accuracy of this method have been verified by citing examples of engineering projects in the article.
