摘　　要：城市道路中央隔离护栏在与车辆发生碰撞事故时易形成开口薄壁长杆,从而对乘员和行人造成伤害。针对这一问题,设计了一种整体框架式护栏方案,建立并进行了碰撞仿真验证。结果表明,这种新型护栏被撞后不易形成开口薄壁长杆,安全性有所提高,为城市道路中央隔离护栏的设计及标准制定提供参考。The central isolation guardrail of urban road is easy to form open thin-wall long rod in the event of traffic accident,thus causing harm to occupants and pedestrians.In order to solve this problem,a design optimization scheme is put forward.,and a frame guardrail is established and verified by collision simulation.The results show that the new guardrail is not easy to form an open thinwall long rod after being hit,and the safety is improved,which can provide a reference for the design and standard formulation of the central isolation guardrail of urban roads.
