以水官高速公路扩建工程中央分隔带护栏改造设计为例,采用理论分析和方案对比相结合的方式,对城区高速公路扩建工程中央分隔带护栏防撞等级确定及型式选择方法进行研究。结果表明:中央分隔带护栏改造设计应结合规范要求和项目实际需求,分别确定路基段、桥梁段护栏防撞等级;应从景观效果、经济性、养护难度、绿化空间等多方面进行比选,确定最优的护栏型式。
以水官高速公路擴建工程中央分隔帶護欄改造設計為例,採用理論分析和方案對比相結閤的方式,對城區高速公路擴建工程中央分隔帶護欄防撞等級確定及型式選擇方法進行研究。結果錶明:中央分隔帶護欄改造設計應結閤規範要求和項目實際需求,分彆確定路基段、橋樑段護欄防撞等級;應從景觀效果、經濟性、養護難度、綠化空間等多方麵進行比選,確定最優的護欄型式。

with design of transformation for guardrails of median strips in Shuiguan Expressway as an example,and in the mode of combining theoretical analysis and solution comparison,this paper researches determination of collision avoidance levels and type selection methods of guardrails of median strips in widening projects of urban expressways.The results show that design of transformation for guardrails of median strips should combine with the requirements of specifications and actual needs of projects to determine collision avoidance levels of guardrails at roadbed and bridge sections;and compare and select based on landscape effect,economy,maintenance difficulty and greening space,etc.so as to determine the optimal guardrail type.
