摘　　要：选取西部山区某隧道路段作为研究对象,基于行车动力学仿真软件,建立项目实际线形状况的道路模型,开展了大车、小车在单坡固定轨迹工况下、双向路拱换道行为工况下的仿真试验,选取了横向偏移指标、质心侧偏角、侧向加速度、横摆角速度等指标,综合分析货车和小车对侧向偏移的承受能力,确定了道路横坡设定的极限条件,可为道路横坡处治时超高设计优化提供参考依据。This paper selects a tunnel section in a mountainous area in the west as the research object,and based on the vehicle dynamics simulation software,a road model according to the actual alignment conditions of the project.Simulation experiments were conducted on the overtaking behavior of large and small vehicles under single-slope fixed conditions and under bidirectional road arches.Indicators such as lateral displacement,centroid lateral inclination angle,lateral acceleration,and lateral angular velocity were selected toensively analyze the tolerance of trucks and passenger cars to lateral displacement,and to determine the limit conditions for road cross-slope settings,which can be used for the of superelevation design in cross-slope treatment schemes.
