摘　　要：我国公路设计相关规范中关于隧道与互通式立交安全间距的设计要求较为笼统模糊。为了进一步科学界定该间距,以单侧三车道隧道公路为依托,基于交通冲突技术利用计算机仿真软件进行定量分析,并从研究驾驶员行车特性的视角建立安全间距计算模型进行补充分析,综合确定了设计速度分别为60、70、80、90、100、110、120km/h的隧道与互通式立交安全间距的推荐值。最后利用数据分析软件拟合出安全间距与设计速度之间的关系函数式,为上述领域进一步研究及应用成果推广提供参考。The design requirements about safety distance between tunnel and interchange in the highway design criterion are unspecific. In order to confirm the distance, depending on unilateral three - lane highway tunnel, the paper used simulation software for quantitative analysis based on traffic conflict technique. Then it made additional analyses according to distance calculation modeling from the perspective of driving characteristics. After that, it comprehensively determineed the recommended values of safety distance that were applied to tunnels with the design speeds of 60 , 7 0 , 8 0, 90 , 100, 110 and 120 km /h. Finally it used data analysis software to fit the relationship between safety distance and design speed, which can be a reference for further research and application results promotion in this field.
