摘要
由于经济的宏观调控以及社会发展的需要,公路建设的重心已经逐步从东部沿海地区向中部及西北地区转移,但是在我国中西部区域山地较多,受到地形地貌因素的影响,使公路长大下坡路段的数量持续增加,坡的长度也在逐渐增长。而连续下坡路段由于受到环境、线形设计等多个因素的影响,导致该区域事故频发。论文结合连续下坡路段事故发生的影响因素进行了深入分析,并通过运行速度的变化特征对连续长大下坡路段的线形加以优化,提出了连续纵坡路段交通安全保障措施。
Due to the need of economic macro-control and social development,the center of gravity of highway construction has gradually shifted from the eastern coastal areas to the central and northwestern regions.However,in the central and western regions of our country,there are many mountainous areas,which are affected by topography and geomorphological factors,so that the number of long downhill sections of the highway continues to increase,and the length of the slope is also gradually increasing.The continuous downhill section is affected by environment,linear design and other factors,resulting in frequent accidents in this area.In this paper,the influencing factors of accidents in continuous downhill sections are deeply analyzed,and the linear shape of continuous long downhill sections is optimized by the variation characteristics of running speed,and the traffic safety measures of continuous longitudinal slope sections are put forward.
