摘　　要：在明确山区高速公路安全性分析与安全设施设计特点的基础上,论文重点分析了长大下坡路段安全设施的分段设计策略,同时,提出了特大桥梁路段、公路隧道路段以及其他路段的设计要点,以充分发挥标志、标线、护栏、诱导设施、缓冲设施等的组合作用,为驾驶人员提供良好的引导和保护,降低交通事故的发生概率。On the basis of clarifying the characteristics of safety analysis and safety facilities design of mountain highways,this paper focuses on the segmented design strategy of safety facilities of long downhill sections.At the same time,it puts forward the design points of large bridge sections,highway tunnel sections and other sections to give full play to the combination of signs,marking,guardrail,induction facilities and buffer facilities,and provide good guidance and protection for drivers to reduce the probability of traffic accidents.
