摘要
提出了一种可以指导护栏结构设计和选型的公路护栏安全性能星级评定方法,研究确定了评价指标和评分标准。该星级评定方法对4种通过A级(160 kJ)实车足尺碰撞试验验证的护栏进行安全性能星级评定,结果为:A级三波护栏二级(★★)、A级钢背竹景观护栏三级(★★★)、A级梁柱式护栏四级(★★★★)、A级直墙型混凝土护栏五级(★★★★★)。星级评定结果与护栏安全性能表现一致,评价指标和评分标准合理,星级评定方法可作为护栏选型的一种依据。星级高的护栏安全性能更优,在交通组成复杂、交通事故多发路段可优先选用。
The star-rating evaluation of highway barriers is presented,and the evaluation indexes and scoring standard of star-rating evaluation of highway barriers was studied and determined,in order to guide the structural design and selection of barrier types.Four barriers which had been verified by full-scale crash test of A-class(160 kJ)vehicles were evaluated by star-rating evaluation of highway barriers.The evaluation results are as follows A-class 3-w barriers is Level 2(★★),A-class steel-bamboo barriers is Level 3(★★★),A-class beam-post barriers is level 4(★★★★),A-class straight concrete barriers is level 5(★★★★★).The result of star-rating is consistent with the safety performance of guardrail,and the evaluation indexes and scoring standard are reasonable.The star-rating evaluation of highway barriers can be used as a basis for the selection of barrier types.It can be preferred in the section with multiple types of vehicle types and the high frequency section of traffic accident,the higher Star-rating the better safety performance.
