通过力学计算分析了半柔性路面在标准荷载及超载作用下的力学响应,结果表明:轮隙中心点下的半刚性基层层底拉应力最大;荷载作用中心点下处的路表弯沉、面层层底拉应变和面层内最大剪应力最大;路表最大弯沉值、面层层底最大拉应变、面层内最大剪应力及半刚性基层底最大拉应力都随着轴载的增加而增大。
The mechanical response of semi-flexible pavement under standard load and overloading is analyzed through mechanical calculation. The results show that the bottom tensile stress of the semi-rigid base under the central point of the wheel gap is the largest; The maximum strain at the bottom layer and the maximum shear stress in the surface layer are the maximum. The maximum deflection of the road surface, the maximum tensile strain at the top of the surface layer, the maximum shear stress in the surface layer and the maximum tensile stress at the bottom of the semi- Increase.
