公路护栏不得侵入公路建筑限界以内,且应与建筑限界的两侧边界线保持合适距离。首先总结了护栏缩进的常见取值和常见问题;然后以高速公路A、Am级波形梁护栏和混凝土护栏为例,分析了波形梁护栏、混凝土护栏缩进值的影响因素,并给出了合理的取值建议;并对较窄的中央分隔带适用的护栏做出了研究和建议。
This paper summarized the common values and common problems of the guardrail indentation.Taking the highway A and Am-level waveform beam guardrail and the concrete guardrail as an example, it also analyzed the influence factors of indentation value and gave the reasonable value suggestion, and also proposed the research and suggestion on the guardrail that applied in a narrow central separation zone.
