Abstract

Abstract: For current rapid development of urban highway problems，control method of barrier failure point on reconstruction project median barrier was proposed，which made the destruction of the barrier component could be controlled when it was collided by vehicle． Based on the method a new type barrier structure was studied． The results by computer simulation displayed that this barrier can not only achieve requirements for landscape，convenient repair and maintenance but also its crashworthiness can reach SB/SBm level．

Key words: barrier, simulation, failure point, control, crashworthiness

摘要： 针对目前我国城区高速公路的快速发展问题，提出了扩建工程中中央分隔带护栏的破坏点控制方法，使护栏在遭受车辆碰撞时，构件破坏位置“可控”，依据该方法研究了一种新型护栏结构型式。计算机仿真分析表明: 该护栏结构型式满足城区高速公路对景观要求高、维修养护方便等方面的要求，其防撞等级可达到SB/SBm 级。
