Abstract: In order to study the differences in predicting the wind speed distribution in section of U-shape steel supporting three-core arch roadway with different turbulence models, the measured wind speed data of wind tunnel under the same boundary conditions were used to compare with the simulation wind speed data based on the standard k-epsilon model, standard k-omega model and Spalart-Allmaras model respectively. The results show that the three turbulence models can approx mately describe the characteristics of roadway airflow. The absolute error between the measured and simulated wind speeds at the cross-section of the roadway is positively correlated with the inlet wind speed, and negatively correlated with the distance from the wall. Taking the mean absolute error and the root mean square error as the evaluation criteria, the standard k-epsilon model has a higher fitting degree with the field measured wind speed data in the simulation of roadway airflow velocity, followed by the Spalart-Allmaras model and the standard k-omega model respectively.
