利用ANSYS软件,建立了半刚性基层沥青路面结构三维模型,分析了在相同垂直荷载和3种不同水平荷载作用下,基面层层间接触状态分别处于完全连续、完全光滑和半连续状态时的路面结构最大剪应力。结果表明:随着水平力的增加,沥青面层内的最大剪应力显著增大,且最大剪应力的位置在深度方向上有向上移动的趋势;在相同的水平力作用下,面层和基层层间光滑和半连续状态比完全连续状态时路面结构最大剪应力均有不同程度地增加;路面结构中层间接触条件将增加面层内高应力区的范围。
Using ANSYS software, a three-dimensional model of semi-rigid base asphalt pavement structure is established. Under the same vertical load and three different horizontal loads, the contact states between the base layers are completely continuous, completely smooth and semi-continuous Pavement structure maximum shear stress. The results show that with the increase of horizontal force, the maximum shear stress in asphalt surface layer increases significantly and the location of maximum shear stress tends to move upwards in the depth direction. Under the same horizontal force, The maximum shear stress of the pavement structure increases with the increase of the inter-layer contact conditions in the smooth and semi-continuous state of the pavement compared with the completely continuous state.
