| Abstract: | Based on the anchor beam project of an underground workshop,the temperature test was carried out for the construction section of rock anchor beams poured firstly.Using the measured data,the back analysis of temperature fields was conducted to obtain adiabatic temperature curves of the concrete and heat-exchange coefficients of different materials using the improved genetic algorithm and theoretically accurate calculation method of three-dimensional finite element temperature field containing cooling water pipes,and the rationality of the results was verified which provided the conditions for the simulation analysis of the subsequent construction of rock anchor beams. |
