以水平荷载及沥青面层厚度作为变量，基于弹性层状体系理论，采用壳牌设计软件 BISAR 3．0和有限元软件 ABAQUS，计算分析了常温下连续配筋水泥混凝土沥青面层复合式隧道路面沥青面层的正应力与剪应力分布情况、面层表面磨耗层与下卧层层间最大剪应力及相应的正应力分布情况。结果表明：由于下承层为刚性基层，沥青面层层底出现较大的压应力，而沥青层表面出现较大的拉应力。不考虑水平荷载时，沥青面层最大拉应力出现在沥青面层表面横行轮迹边缘，最大剪应力出现在距沥青表面4．5 cm 处的轮底中央；考虑水平荷载时，沥青面层最大拉应力出现在沥青面层表面行车方向轮迹边缘，最大剪应力出现在沥青面层表面轮迹边缘。沥青表面层与下卧层之间最大剪应力随附着系数的增大而增大，随沥青表面层厚度的增大而减小，对应的正应力均为压应力。

This paper makes a calculation and analysis of the distribution on tensile stress and shear stress of asphalt layer,on maximum shear stress and the corresponding normal stress between wear-ing layer and substratum,by using Shell design software BISAR 3.0 and the finite element software ABAQUS.The results show that the bottom of the asphalt layer appears larger compressive stress,the as-phalt surface layer appears larger tensile stress ,as the bearing layer is rigid.Regardless of the horizontal load,the asphalt layer maximum tensile stress appears transverse edge of the wheel track on the surface of asphalt layer,and maximum shear stress appears wheel bottom central below 4.5 cm off the surface;Considering horizontal load,maximum tensile stress appears the edge of the wheel track along the driving direction on the asphalt surface layer ,and the maximum shear stress appears the edge of the wheel track on the asphalt surface layer.The maximum shear stress increases with adhesion coefficient increasing be-tween asphalt surface layer and substratum,and decreases with thickness of asphalt surface layer increas-ing,which corresponding normal stress is compressive stress.
