| 摘 要： | 采用实测轮胎接地有效面积和接地压力,通过编写Fortran程序将交通荷载转化为移动均布荷载,对三维多层的沥青路面进行有限元动态分析,得到路面沥青结构层剪应力沿深度方向的分布规律.结果表明,不同荷载条件下路面沥青层剪应力的差异明显,水平力对剪应力亦有较大影响;路面面层回弹模量、泊松比及基层回弹模量对剪应力的影响均比较显著.

| Abstract: | Tire-pavement contact pressure is measured and the Fortran procedure is employed to deeply analyze shear stress in flexible and semi-rigid pavement by 3D finite element method.The calculating results show that vertical contact pressures and horizontal stress as well as structure parameters including surface Poisson ratio,base and surface modulus can affect shear stress. |
