摘　　要：山区公路工程设计过程中,必须更加重视安全分项设计,尤其是在危险路段,应妥善调查各种潜在的交通安全风险源,并根据具体的风险源类型制定针对性的安全设计方案。本文以山区危险路段的线形特点为研究背景,选取平曲线半径和横坡率两个指标作为研究对象,定量分析了两种指标对线形安全的影响,并从曲率变化协调性和行车视距合理性角度对山区危险路段安全性进行分析,提出了相应的设计参考及控制措施。In the design process of mountain highway engineering,more attention should be paid to the safety sub-item design,especially in dangerous sections. Potential sources of traffic safety risks should be properly investigated and specific safety design schemes should be formulated according to the specific types of sources of risk. This paper takes the alignment characteristics of dangerous sections in mountain areas as the research background,and then chooses the safety sub-item design as the research background. Taking the radius of horizontal curve and the rate of cross slope as the research object,the influence of the two indexes on the safety of alignment is analyzed quantitatively,and the safety of dangerous sections in mountainous areas is analyzed from the perspectives of curvature coordination and driving sight distance rationality,and the corresponding design reference and control measures are put forward.
