高速公路长大下坡路段安全设施系统设计

Long Downhill Road Safety Support Facilities System Design

高速公路长大下坡路段存在一定的安全隐患,为改善这一路段的行车安全并减少事故,对其安全设施的设置与设计进行必要的研究具有现实意义。通过对长大下坡路事故成因分析,从主动型防护和被动型防护两个方面提出了一种高速公路连续长大下坡路段安全设施设置与设计技术路线,分析了设置完整的安全保障体系的方法,并以重型载重车辆通过橡胶空腔减速垄为例做了仿真分析,结果表明减速效果良好。

There are some potential safety hazards in long and steep downhill sections of expressways.In order to improve traffic safety and reduce accidents in this section,it has practical significance for carrying out necessary research on the setting and design of safety facilities.Based on the analysis of the causes of long and steep downhill accidents,a technical route for setting up and designing safety facilities in continuous long and steep downhill sections of expressways is proposed from two aspects of active protection and passive protection.The method of setting up a complete safety guarantee system is analyzed.The simulation analysis is carried out by taking heavy-duty vehicles passing through rubber cavity deceleration ridges as an example,and the results show that the deceleration effect is good.
