Abstract:
5 male and 3 female drivers were selected, their increased rate of heart beat were got in the experiment sections in Qinling tunnel, and the heart rate changes in different drivers were analyzed. According to the measured data, the quantitative model between longitudinal slope of freeway tunnel and drivers' increased rate of heart beat was established, and longitudinal slope of freeway tunnel and running speed was established with regression analysis. Analysis result shows that the longitudinal slope of freeway tunnel has important influence on divers' rate of heart beat. The safe slope of the tunnel and security speed were calculated according to the model. 6 tabs, 9 figs, 7 refs.
