本文叙述了我国在越江公路隧道中首次应用反光安全导标的情况。文中主要介绍了在隧道内设置安全导标的间距计算经验公式。这些公式可以考虑不同车速和不同道路曲率半径对确定设置间距的影响。同时,对路面设标和侧墙设标提供了独立的计算公式。
This article describes the first time in our country in the cross-river tunnel reflective reflective safety guidelines. This paper mainly introduces the empirical formula of calculating the distance between safety guides in the tunnel. These formulas take into account the effect of different vehicle speeds and different road curvature radii on determining the set spacing. At the same time, the pavement marking and the side wall marking provided an independent formula.
