城市道路用新型中分带护栏开发

结合依托工程,参考国内外相关标准,综合城市快速路桥梁交通流状况、景观以及维护要求等因素,提出一种新型城市用中央分隔带护栏结构,运用有限元仿真技术对其进行优化和安全防护性能评价。结果表明,新型中央分隔带护栏结构能够有效阻挡车辆,护栏各项指标均满足评价标准要求,防撞等级达到Am级,适用于城市快速路中央分隔带。

Development of New Median Strip Barrier for Urban Road

By depending on the projects,referring the relevant standards at home and abroad,and synthesizing the factors of bridge traffic flow status,landscape and maintenance requirements of the urban expressways,the article puts forward a new structure of the urban median strip barrier,optimizes it by the finite element simulation technology and evaluates the security and preventive performance.The result makes clear that the new structure of the urban median strip barrier can efficiently stop the vehicles,and the various indexes of barrier can satisfy the evaluation standards and requirements.The crash-proof class is Class Am,which is suitable for the median strip of urban expressway.
