摘　　要：通过计算机仿真方法和实车足尺碰撞试验验证等手段,研究提出了一种新型A级波形梁钢护栏与SB级混凝土护栏过渡段结构形式,该结构防撞等级达到A级,碰撞能量160 k J,经试验验证,各项性能指标符合交通行业标准要求,新的护栏过渡段可实现不同防护等级的公路护栏之间连接平顺、结构刚度平稳过渡。Through finite element simulation method and full-scale impact test with real vehicle,the study developed a new type of transition section between A level w-beam barrier and SB level concrete barrier. The safety performance of the new transition section reaches A level,160 kJ. Verified by the impact test,all items meet requirement of relevant transportation standards. The new transition section is capable to accomplish smooth connection and stiffness transition between different barriers.
