摘要
以石安高速公路为例,提出两种满足新规范的原护栏利用改造方案,利用有限元模拟方法对其进行整体防撞性能评价,得出较优方案,并进行实车碰撞试验。优化改造方案可使其具有更大的防护空间,不但可以减少很多的工作量,降低对道路运营的影响,还可以节省大量的费用,适用于我国道路交通条件相似的高速公路。
Taking Shijiazhuang-Anyang Expressway as an example, it proposes two kinds of barriers reconstruction that conforms to the new specifications, evaluates the anti-impact performance with the finite element simulation method and conducts real vehicle collision experiment to come to a better scheme. Optimizing the rehabilitation program to increase protective energy will not only reduce lots of workload and the impact to operations, but also save a lot of fees, which is suitable for the expressways with similar traffic conditions in China.
