摘要
为解决山区沥青路面上坡路段严重的车辙破坏,通过对上坡路段车辆行驶特性的分析,计算车辆对路面结构的水平和垂直荷载。通过建立道路三维有限元模型,分析山区沥青路面车辆荷载对结构剪应力的影响,采用合理的结构设计和纵坡技术指标,提高山区沥青路面抗剪切性能。
To overcome serious rut failure on upgrade road section of asphalt pavement in mountain area, by analysis of operational characteristics of vehicle on upgrade road section the calculation of horizontal and vertical loads of vehicle to pavement structure is carried out. Through establishment of three - dimensional finite element model for rad,the paper analyzes impact of vehicle load on structure shear stress of asphalt pavement in mountain area,adopts rational design of structure and qualifications for longitudinal grade, increasing the shear resistance of asphalt pavement in mountain area.
