摘　　要：由于山区公路交通安全形势较为严峻,在道路设计上,现行的山区公路设计均统一采用通用的公路工程设计标准,缺乏在一定横风作用下平曲线半径设定的参考标准取值。为了减少或避免交通安全事故的发生,本文重点以影响交通安全的山区道路平曲线最小半径可能产生的设计缺陷为切入点进行分析,采用相关试验得出在不同风速、不同设计行车速度下山区公路平曲线最小半径设计参考值,从理论上解决设计缺陷对山区公路交通行车安全的影响。due to the traffic safety situation is more severe in roaddesign, design of the current highway are unified by highwayengineering design standard, lacking in a crosswind flat referencestandard value of curve radius set. In order to reduce or avoid theoccurrence of traffic accidents, this article focuses on the designdefects of the minimum radius of horizontal curve of mountainroad traffic safety may be produced as the starting point for theanalysis, the relevant test results of mountain area highwayminimum radius of horizontal curve design reference value indifferent wind speed and different design speed, solve the designdefects of traffic the mountain highway safety theoretically.
