摘要: 针对长大下坡路段隧道入口处的钢护栏结构,采用结构刚度设计原理进行设计,并通过计算机仿真方法分别对大型车和小型车与护栏的碰撞过程进行了分析研究。研究结果表明:该钢护栏结构的防护等级可达到SA级,有利于降低车辆尤其是大型车辆撞击到隧道口壁的事故发生,有效降低长下坡路段隧道入口处的事故严重程度。

Abstract: According to the steel rail structure of tunnel entrance in section of the long and steep downgrades, the structure research on the steel rail structure at the tunnel entrance was carried out. The type of the steel structure was designed in the principle of the structure stiffness design, and the crash processes of large and small vehicles and rail were studied by the method of computer simulation. The results show that the protection level of the steel rail structure can reach SA level, and it is also good for reducing accidents of the vehicles especially large vehicles impacting to the tunnel entrance wall, which effectively reduces the severity of the accident at tunnel entrance in section of the long and steep downgrades.

Key words: road engineering, long and steep downgrades, steel rail, computer simulation, tunnel entrance, crash
