摘要
为使改扩建高速公路临时港湾停车带混凝土预制块结构达到A级防护等级,对临时港湾停车带进行改造,改造结构由混凝土预制块、三波梁板及连接构件组成,通过仿真分析《公路护栏安全性能评价标准》(JTG B05-01—2013)规定的三(A)级碰撞条件,验证其防撞性能。为判断文章采用的改造方法的效果,进行了仿真分析,通过分析仿真结果,可知在改造完成后,停车带护栏的防撞性能满足规范要求。
In order to make the concrete prefabricated block structure of the temporary harbor parking belt on the expanded and reconstructed expressway reach the A-level protection level,the temporary harbor parking belt is reconstructed.The reconstructed structure is composed of concrete prefabricated blocks,three wave beam plates and connecting members.Through the simulation analysis of the three(A)level collision conditions specified in the Standard for Safety Performance Evaluation of Highway Barriers(JTG B05-01-2013),the anti-collision performance is verified.In order to judge the effect of the reconstruction method adopted in this paper,the simulation analysis is carried out.By analyzing the simulation results,it can be seen that after the reconstruction is completed,the anti-collision performance of the parking belt barriermeets the specification requirements.
