摘  要:
竖曲线是道路基本线形形式之一,并且是道路线形设计关键控制点。草原公路竖曲线具有变坡点多、坡长变化范围大的特点。本文通过偏相关分析方法确定草原公路纵坡路段影响驾驶员心电特性的线形要素为坡度,运用数理统计方法建立驾驶员心率增量与坡度的关系模型。得出在草原公路上坡路段当坡度为3.1%时,驾驶员心率增量达到最大值,驾驶员在此坡段精神负荷最大,疲劳感增强。

摘  要:
Vertical curve is one of road alignments and the key control point.Vertical curve of prairie highway has the features of many grade change points and large slope length range.Through the partial correlation analysis method,this article obtains that the alignment of influencing drivers' ECG is slope in the section of longitudinal gradient on prairie highway.And applying the mathematical statistic method,it establishes model of relationship between the HR growth and slope.It concludes when slope is 3.1% in upslope sections the drivers' HR growth and mental load reaches maximum,and tiredness strengthens.
