摘　　要：运用数学统计、概率分析等方法对山区高速公路隧道口与互通式立交口之间的安全距离问题进行分析,研究了影响双向6车道高速公路隧道口与互通式立交口之间净距离的各种因素关系。结果得出山区高速公路隧道口与互通式立交口之间最小净距离的标准,并对已建山区高速公路中隧道口与互通式立交口之间距离不足问题提出处治措施,以提升山区高速公路的驾驶安全。Mathematical statistics and probability analysis are applied to analyze the safe distance between tunnel portal and interchange of expressway in mountain area. Various influence factors of the net distance between the tunnel portal of two-way six-lane expressway and the interchange entrance are studied. The standard of minimum net distance between the tunnel portal of the expressway in mountain area and the interchange entrance is obtained. The treatment measures for the tunnel portal and interchange of the completed expressway are put forward so as to enhance the driving safety of the highway in mountain area.
