几种危险路段护栏设计探讨

Design of Fences for Several Kinds of Dangerous Sections

对几种危险路段的事故危险特征和设计缺陷的分析,重点介绍了极限最小半径曲线路段、隧道洞口、长直线末端接一般最小半径曲线路段、连续长陡下坡路段护栏设计。通过建立计算模型等模式深入探讨护栏设计方法及技术解决措施,旨在设计出满足道路使用需求的护栏,充分保护道路使用者的安全。

This paper analyzes the dangerous features of the accidents and dangerous sections. It highlights of the curve road for the end o Through building the calculation measures to design the fence whi the limited minimum radius of the curve road, designs defects of several kinds of tunnel portal, the minimum radius f the long straight line, the offence design for continuous long steep downhill model, this paper deeply discusses the design methods and techniques of solving ch meet the using requirements of the road and protect the safety of the road users.
