遮風壁による高架橋上の車両への遮風効果

抄録

Parapets, noise barriers and through girders, hereafter referred to as the wall, which have 100% solidity ratio are not built for the wind protection. However, the wind protection effect can be expected as long as the height of the wall or the distance between the wall and the vehicle meets certain criteria. Then, in order to confirm the wind protection effect, we carried out the wind tunnel tests. On the basis of the test results, we arranged the conditions for the windbreak wall which have a windbreak effect equal to or better than that of windbreak fence (the height is R.L.2m and the distance to the center of the vehicle is 3m).
