摘　　要：为进行广深高速路侧护栏升级改造研究,对广深高速既有护栏结构进行分析,同时对比“新标准”和“新老规范”对护栏设计和安全的规定,可知广深高速既有A级波形梁护栏不满足“新标准”和“新规范”的要求,需进行升级改造。结合广深高速对路侧护栏景观效果和安全性需求,提出A级和SB级梁柱式型钢护栏的升级改造方案,此方案护栏结构美观,安全防护性能满足标准要求,且安全防护性能和景观效果较既有波形梁护栏有较大提升,能有效改善广深高速路侧护栏的防护水平和景观效果。In order to research on Guangzhou-Shenzhen highway barriers upgrading and rebuilding, the structure of the existing barriers was analyzed, standard for safety performance evaluation of highway barriers and design specifications for highway safety facilities were compared. It could be seen that the existing barriers didn't meet requirement of "new standard" and "new specification", and it was necessary to upgrade for the barriers. Based on landscape and safety requirements of Guangzhou-Shenzhen highway, the structures of A-level and SB-level girder-and-post steel barriers were designed. Safety performance and landscape of A-level and SB-level girder-and-post steel barriers met the requirements of the evaluation standard, which were better than Guangzhou-Shenzhen original highway barriers', and the structures were beautiful. Therefore, the upgrading and rebuilding program effectively improved the safety level and landscape effect of Guangzhou-Shenzhen highway roadside barriers.
