Relationship of Linear Combination of Tunnel and Heart Rate Increase Rate

In order to ensure Mountain highway tunnel traffic safety, improve the linear combination of the tunnel design, we set up a model about heart rate increase rate and the linear combination of the tunnel design, using dynamic physiological detector records physiological data in real car test, and using the theory and method of mathematical statistics and mathematical modeling, analysis of the relationship between heart rate increase rate and bend radius, slope and length of the tunnel and set up some regression models by SPSS, analyzed and compared the effectiveness of each model. Analyze draw, it's very significant to linear correlation between heart rate increase rate and the combination of bend radius, slope and length of the downhill tunnel, while the uphill tunnel section was not significant. According to the regression model, we known the discipline about the changes of heart rate increase rate with tunnel design(i, R, L)combination, and the relationship between L and R in critical conditions: when the longitudinal slope is less than 36.38 ߮, R / L =0.606, When longitudinal greater than 36.38 ߮, L / R = 0.645.
