Analysis on the Wind Flow Measuring of Surrounding Areas in Accordance with Installation of Road Facilities

摘要

As 70% of the terrain of Korea consists of mountains, it is required to incorporate embankments, bridges and tunnels, etc. into road construction plans. The change in wind flow caused by the construction of embankment, in particular, has led to the increase of wind flow damage. In this study, a research was conducted on the method to facilitate wind flow, changed by the road embankment using culvert. There were a total of 52 points, of which 26 points were in front of the road embankment and 26 points in the back of the road embankment. When the number of two culverts were the same, the wind speed around the culvert was greater by more than 5% ～ 40% in the culvert size 6.0m × 4.5m than in the culver size 3.0m × 2.5m. The findings of the experiment indicates that the reduced wind speed of the wind flow entering and passing through the inlet of culvert can mitigate the congestion of wind flow that would otherwise be caused by the installation of the culvert.
