摘要
针对宝三高速公路采用何种护栏方式既能满足高速公路规范要求和安全需要又能最大限度地减少后期运营成本进行了多次探讨和完善,最终确定中央分隔带全部采用波形梁护栏,路侧直线低路基地段尝试性地采用了柔性缆索护栏。经过寒冷冬季雪情实践证明,采用缆索护栏总体效果较好,冬季养护成本较低,安全性更有保障。文章从冬季养护成本方面探讨缆索护栏在锡盟地区高速公路的适应性和应用前景。
After many discussions on using which guardrail on Baochang to Sanhaodi highway can not only meet requirements of highway specification and safety,but also furthest reduce later operation cost,the paper finally determines the scheme that median strips all use W-beam guardrails and straight low subgrade sections in road sides tentatively use flexible cable guardrails.The engineering practice through snow days in cold winter proves that the overall using effect of cable guardrails is better,the maintenance cost in winter is lower and the safety is more security.The paper discusses the adaptability and application prospect of cable guardrails on highway in Xilinguole league in terms of winter maintenance cost.
