摘　　要：高速公路中央分隔带采用整体式混凝土护栏对于交通安全较为适用,可有效防止一侧发生交通事故对另一侧交通安全带来的影响。列出混凝土护栏的防护等级与汽车碰撞荷载的对应关系,论述采用屈服线理论计算混凝土护栏防护能力的方法及适用条件,并根据工程实例提出了优化设计方案。所提出的设计方案可为相关设计人员提供参考。The integrated concrete guardrail used in the central partition of highway is more suitable for traffic safety,which can effectively prevent the impact of traffic accidents on the other side of traffic safety.The corresponding relationship between the protection grade of concrete guardrail and the collision load of automobile is listed with the method of calculating the protection capacity of concrete guardrail by the yield line theory and the applicable conditions discussed to put forward the optimal design scheme according to the engineering example.The proposed design scheme can provide reference for relevant designers.
