| 摘 要： | 应用有限元分析方法分析超载、水平荷载和路面坡度三个因素对下坡路段沥青路面层间剪应力的影响。分析结果显示三个因素对沥青路面结构层层底的剪应力都有不同程度的影响,其中车辆超载影响最为明显,水平力次之。当超载、水平力和坡度三个因素联合作用时,会使得破坏极为严重。因此为了有效地控制下坡路段沥青路面的滑移破坏,应当严格限制车辆的超载、纵坡的坡度和减少紧急制动。

| Abstract: | Finite element analysis method is applied to analyze the influence of three factors like overload,horizontal load and pavement slope on the shear stress between layers of down-slope section of asphalt pavement.The analysis results show that three factors exert different influences at different level on the shear stress at the bottom layer of asphalt pavement structural layer,among which the influence of vehicle overload is the most obvious and horizontal force takes the second place.When three factors like ... |
