Study on the Safe Distance between Interchange Entrance and Tunnel Portal of Expressway in Mountain Area |
| |
| Abstract: | 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. |
