Abstract
In this paper, through numerical simulation, the modulation effect of trees on the wind field of the highway and the wind load of the traffic is studied. Two tree species were selected, and the effects of different tree species and arrangement numbers on the wind speed on the embankment and the wind pressure on the driving surface were studied, by simulating the single-row distribution of a single tree species and the mixed multi-row distribution of two tree species. The results show that trees play a significant role in wind field modulation, and different tree species have different effects; Compared with the modulation of single tree species, the mixed modulation effect is more effective, and gradually increases with the number of rows, but the trend of enhancement gradually slows down.
