摘　　要：为了研究桥头搭板与路基路面结构一体化的有效评价路径,结合云贵高速武定桥工程项目,以有限元分析理论的核心内容作为理论基础,再通过借助ANSYS软件开展云贵高速武定桥桥头搭板与路基路面结构一体化的模型建立和数值分析。从模型数值分析结果可以看出,云贵高速武定桥桥头搭板与路基路面临界衔接区段在外力均质荷载70 kN的作用下,距离衔接接触中点0.3 m处、0.5 m处、0.7 m处的稳定状态位移量非常小,发生桥头跳车现象的可能性低。从而实现对于云贵高度武定桥桥头搭板与路基路面结构一体化的设计效果评价。In order to study the effective evaluation path of the integration of approach slab and subgrade and pavement structure,combined with the project of Wuding Bridge of Yunnan Guizhou Expressway,the model establishment and numerical analysis of the integration of approach slab and subgrade and pavement structure of Wuding Bridge of Yunnan Guizhou Expressway are carried out with the help of ANSYS software based on the core content of finite element analysis theory.It can be seen from the numerical analysis results of the model that under the action of an external uniform load of 70 kN,the stable state displacement at 0.3 m,0.5 m and 0.7 m from the midpoint of the connection contact is very small in the junction section between the approach slab at the bridgehead and the subgrade road of Wuding Bridge on Yunnan Guizhou Expressway,and the possibility of vehicle bump at the bridgehead is low.So as to realize the evaluation of the design effect of the integration of the approach slab at the bridgehead and the subgrade and pavement structure of Wuding Bridge at Yunnan Guizhou height.
