摘　　要：在今天交通运输业发达的背景下,我国兴建了大量的高速公路。然而,这些高速公路在运行中经常发生交通事故。为了保障公路交通的安全,防撞护栏作为一项重要的交通安全设施,需要具备强大的防撞性能。针对大货车和小轿车与防撞护栏碰撞易出现的侧翻和下钻等现象,提出了一种优化方案,即通过加高防撞护栏并采用双层波形梁结构,以提高护栏的防撞性能,并减小事故的危害。Against the backdrop of today’s developed transportation industry,China has built a large number of highways.However,these highways often experience traffic accidents during operation.In order to ensure the safety of highway traffic,anti-collision guardrails,as an important traffic safety facility,need to have strong anti-collision performance.This article proposes an optimization plan to address the issues of rollover and drilling in collisions between large trucks and small cars and crash barriers.The plan involves increasing the crash barrier and adopting a double-layer corrugated beam structure to improve the crash performance of the barrier and reduce the harm of accidents.
