    • Abstract
  • In order to explore the distribution characteristics of flow fields behind six different types of highway wind barriers and their wind loads, the flow fields above different lanes behind wind barriers and wind loads of the barrier strips at different heights above the ground were tested by a full-scale wind tunnel test. Comparisons of the influence of different pore sizes and opening forms on the flow fields were analyzed. The drag coefficients, moment coefficients and the wind speed reduction coefficients of whole wind barriers were derived. The results showed that the influence of pore sizes on the flow fields behind wind barriers was limited. The influence of opening forms on the flow fields in front of wind barriers was limited. However, the influence of opening forms on the flow fields behind wind barriers was obvious. Due to the impact of the bent cap, the drag coefficient of the top barrier strip was lower than other strips. The wind load coefficients of the whole wind barrier could provide guiding reference for the design of this type of wind barriers.
