摘　　要：针对佛山官西线冷再生路面结构形式,采用有限元BISAR计算软件进行路面力学分析,得到了路面不同深处的位移、应力、应变、剪应力和剪应变.力学分析表明,路面的位移在车轮通过的轮胎正中之轮胎外侧边缘最大,而双轮正中位置的垂直形变最小;竖向应变数值大于水平应变,且3个方向的应变均在路面深度约6cm处达到最大值;随着路面深度的增加,各计算线的应力趋向一致;最大剪应力和剪应变出现均出现在计算线C的位置处.According to the cold recycled pavement structure form of Guanxi line in Foshan,the procedure BISAR as the calculation software was chosen to study the pavement mechanics,the displacement、stress、strain of different road depth were obtained.Mechanical analysis show that the largest road displacement is in the tire lateral edge which in the middle of the tire passed by the wheel,while the minimum vertical deformation is in the wheel center position;vertical strain values is greater than the strain of level,and strain in three directions on the road is about 6cm department under surface can reach the maximum.With the increase of surface depth,the stress of calculation lines convergence;maximum shear stress and shear strain occurs in C department on the calculation line.
