Abstract:
In order to improve the driving safety at tunnel entrance and exit, through analyzing the characteristic of the driving speed variety and the alignment transition demand, the tunnel entrance and exit alignment description model which reflects the horizontal and vertical combination character was established. The driving speed differential was considered as the alignment safety evaluation index and the safety evaluation criterion was also put forward. The relation models of the alignment transition index at tunnel entrance and exit and driving speed differential were set up by using the mathematical modeling method. The results indicate that the driving speed differential at tunnel entrance and exit is related with the alignment transition index and the driving speed of the preceding section. Therefore, during the alignment design of tunnel entrance and exit, the safety evaluation must be consisdered according the recommended value of the alignment transition at different design speed. 7 tabs, 3 figs, 10 refs.
