摘要: 护栏对于桥梁尤其是跨线或跨越河流桥梁交通通行的防护能力越来越受到交通建设和管养部门的重视。以某黄河公路大桥防护护栏设计为例,通过交通流和路侧危险程度分析,首先确定了护栏防护等级,接着确定了护栏外形尺寸,最后对于护栏的立柱抗剪承载能力、公称抗力和尺寸进行了复核验算。结果表明:防护护栏设计能够满足桥梁交通通行的防护要求,且对桥梁承载能力影响较小,美观性和通透率方面均能满足当前交通和环境要求。研究结果对未来类似工程提供可借鉴的理论和工程经验。

Abstract: The protective capacity of guardrails for bridges, especially bridges across lines or rivers, has attracted more and more attention of traffic construction and maintenance departments. Taking the design of protective guardrail for a Yellow River highway bridge as an example, the level of guardrail protection was determined through the analysis of traffic flow and roadside risk degree; and then the shape and size of the guardrail were determined; finally, the shear bearing capacity, nominal resistance and size of the column of the guardrail were checked. The results show that the proposed design of protective guardrail can meet the protection requirements of traffic passage of bridges, and has little influence on the bearing capacity of bridges. The aesthetics and permeability can meet the current traffic and environmental requirements, and the research results can provide the referential theory and engineering experience for similar projects in the future.

Key words: bridge engineering, a Yellow River highway bridge, bridge guardrail, protection level, protection capability check
