摘要
以道贺高速公路为工程背景,采用多种技术手段,进行了公路项目安全性评价,重点介绍了道路安全审计的关键问题;通过对长大下坡路段的安全性分析,赵家特大桥上风速场分析,发现长达下坡路段以及赵家特大桥上的安全隐患,并针对这些安全隐患提出了提高行车安全性的改善建议,以降低事故率。
Based on the engineering background of Dao-He expressway,a road safety audit is carried out using several technical means.Several key issues of road safety audit are emphatically introduced.Based on safety research of long and steep downgrades and analysis of wind speed field on Zhaojia Bridge,some potential safety hazards are pointed out.Suggestions for improvement are given to reduce accident rate.
