摘要
随着我国经济的不断发展,高速公路的建设里程不断增加。同时,车辆组成及车流量特征的巨大的变化,导致交通量及载重量不断增加,群众出行也对公路桥梁过渡段的防护提出了更多的要求。因此,为了避免车辆在桥梁过渡段处发生安全事故,提升公路桥梁过渡段护栏的防护能力迫在眉睫。文章针对免翼墙路基桥梁过渡段护栏设计在高速公路中的应用进行研究,根据路基桥梁过渡段护栏现状和免翼墙路基桥梁过渡段护栏设计原则,提出其结构设计及材料和安装要求,以供参考。
With the continuous development of China's economy,the construction mileage of expressways is constantly increasing.At the same time,the huge changes in the composition of vehicles and the characteristics of traffic flow have led to an increase in traffic volume and load capacity,and public travel has also put forward more requirements for the protection of highway bridge transition sections.Therefore,in order to avoid the safety accidents of vehicles in the transition section of the bridge,it is urgent to improve the protection capacity of the guardrail in the highway bridge transition section.This paper studies the application of guardrail design in the transition section of the non-wing wall subgrade and bridge in the expressway.According to the current situation of the guardrail in the transition section of the subgrade and bridge and the design principle of the guardrail in the transition section of the non-wing wall subgrade and bridge,the structural design and material and installation requirements are put forward for reference.
