摘　　要：阐述了高速公路中分带宽度受限时采用整体式混凝土护栏的意义,介绍了混凝土护栏的防护等级和基础形式,论述了基于屈服线理论的HB级整体式混凝土护栏防护能力的设计方法,重点提出了当该种混凝土护栏采用钢管桩基础时的受力分析模式及优化设计方案。This paper expounds on the significance of adopting the integrated concrete guardrail when the width of the central expressway separation is limited,introduces the protection grade and foundation forms of the concrete guardrails,states the yield-line theory-based design method of class-HB integrated concrete guardrails for protection capacity,and emphasized the force analysis and optimization design solutions when the steel pipe pile foundation is used for this type of concrete guardrail.

关 键 词：混凝土护栏 屈服线理论 桩基础 优化设计
