轻型防撞站石在武汉长江大桥上的应用

城市桥梁由于人行道站石高度不足,容易使车辆在桥面发生意外时越过站石引起坠江事故。结合武汉长江大桥人行道站石改造工程,介绍一种轻型钢筋混凝土结构防撞站石的结构型式和安装施工。采用这一结构,既不增加桥面人行道结构荷载重量,又不影响桥面行车视线和整体美观,施工简单易行,具有较好的防撞效果。

Application of Light Bump-Proof Curb in Wuhan Changjiang River Bridge

The height of curbs on pedestrian walk is not enough for urban bridges, so that it is easy for vehicles to pass over curbs to occur accident of dropping into river, when vehicle occurs accident on the deck. In the combination with the reformation project of curb of pedestrian walk in Wuhan Changjiang River Bridge, the paper introduces a structural type, installation and construction of bump-proof curb of light reinforced concrete structure. To use this structure not only not increases the load weight of deck pedestrian walk structure, but also not influence on the travel vision line on the decking and the integral beautification with easy construction and better bump-proof effect.
