摘　　要：为提高高速公路桥头过渡段路基路面结构的承载能力与稳定性,文章提出了一种全新的过渡段路基路面结构设计方法。首先,确定桥头过渡段的长度,并设计过渡段路基路面结构形式;在此基础上,通过架设桥头过渡段路基路面搭板,实现搭板与路基路面的紧密结合,形成一体化结构。应用分析结果表明,按照该方法设计的路基路面结构具有较高的承载能力,能承受更大的车辆载荷和交通流量,减少路面的损坏和变形,从而延长道路的使用寿命并提高行车安全性。In order to improve the bearing capacity and stability of subgrade and pavement structure in transition section of expressway bridgehead,a new design method of subgrade and pavement structure in transition section is proposed.Firstly,determine the length of the bridgehead transition section,and design the subgrade and pavement structure of the transition section.On this basis,by erecting the subgrade and pavement approach slab of the bridgehead transition section,the close connection between the approach slab and the subgrade and pavement is realized,and an integrated structure is formed.The application analysis results show that the subgrade and pavement structure designed according to this method has higher bearing capacity,can withstand greater vehicle load and trafficflow,reduce the damage and deformation of the pavement,so as to prolong the service life of the road and improve the driving safety.
