摘　　要：文章从隧道洞口内外线形一致性评价、曲线隧道视距评价等方面着手,分析了山区公路隧道安全评价方法,并研究了山区公路隧道线形优化要点,随后以某山区高速公路沿线的长隧道为例,分析了其安全性,并提出了线形优化思路,研究成果可为类似隧道项目设计提供借鉴。This paper analyzes the safety evaluation method of highway tunnel in mountainous areas from the aspects of alignment consistency evaluation inside and outside the tunnel portal and sight distance evaluation of curved tunnel,and studies the key points of alignment optimization of highway tunnel in mountainous areas.Then,taking a long tunnel along a mountainous expressway as an example,its safety is analyzed,and the idea of alignment optimization is put forward.The research results can provide reference for the design of similar tunnel projects.
