Back analysis of non-adiabatic temperature parameters of roller-compacted concrete

The determination of the concrete boundary heat transfer process is the key point of the temperature field and stress field, and it is also the important aspects to investigate the problem - simulation of the critical temperature control of concrete structures. Relying on a project, take a test under the non-adiabatic state temperature of the concrete, and obtain the measured data. Using improved genetic algorithm as a numerical back-analysis method, calculating the measured data inversion of temperature field, and comparing the calculated with the measured values, then analyzed the reasonableness of the inversion results, at the same time we obtained the equivalent heat transfer coefficient with the engineering condition in compliance under the condition of different things cover concrete surface and different sizes cooling water pipe wall, to provide references for similar projects.
