摘要
挑选5名男驾驶人和3名女驾驶人,通过测试获得不同性别驾驶人在通过秦岭某段隧道时的心率增加率,分析不同性别驾驶人心率的变化,采用回归分析的方法,建立隧道纵坡与驾驶人心率增加率、隧道纵坡与速度的关系模型,定量比较了驾驶人在不同隧道纵坡时的心率增加率。分析结果表明:高速公路隧道纵坡的坡度对驾驶人的心率变化率有相当大的影响;并计算得出试验段隧道的安全坡度和上、下坡的汽车安全行驶速度。
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.
