摘　　要：为提高高原公路行车安全，借助动态GPS、多导电生理记录仪等检测设备，对109国道青藏段海拔3567～4709m区间内公路路线形、行车速度和驾驶人生心理反应进行实地检测。以心率增长率为评价指标，确定海拔高度、平曲线半径和车速为影响因素，利用多元回归分析的方法分别建立适用于海拔3567—3957m和4100-4709m的心率变化模型并进行模型检验，最后应用模型结合《公路路线设计规范》（JTGD20—2006）提出不同海拔区间内平曲线半径最小参考值。结果表明：模型精度良好，能够反映驾驶员实际运行过程中的心率增长率变化：海拔3567～3957m区间内平曲线半径应不小于300111，海拔4100～4709m区间内平曲线半径应不小于350In为宜。In order to improve traffic safety on plateau highway, by using dynamic GPS, multi-channels cardiac electrophysiological polygraph and other testing equipments, road alignment, driving speed and drivers＇ psycho- logical and physiological reactions are tested on Qinghai-Tibet Highway of No.109 National Highway with the altitude ranging from 3 567-4 709 m. Taking increased rate of heart rate as the evaluation index and altitude, horizontal radius and driving speed as influencing factors, this study established and tested models of heart rate change applied to the altitude of 3 567-3 957 m and 4 100-4 709 m with the method of multiple regression analysis. Finally, according to Design Specification for Highway Route （JTG D20- 2006）, the minimal reference value of horizontal radius at different altitude intervals was explored. The results indicate that the accuracy of models is favorable, and the models can reflect changes of heart rate growth. The value of horizontal radius with the altitude ranging from 3 567-3 957 m should not be less than 300 m, and with the altitude ranging from 4 100 to 4 709 m it should not be less than 350 m.
