Abstract (English):	Contact pressure between tires and asphalt pavement structures exhibits strong nonuniform distribution characteristics. Pavement mechanical responses under such conditions can be obtained efficiently by numerical simulation. Two specialpurpose programs, Everstress FE developed by 3D finite element method and 3DMove Analysis developed by 3D continuumbased finitelayer approach, were assessed in this study. Their computational principles for simulating nonuniform contact pressure were systematically investigated, and their technical characteristics and differences were compared. Verification was conducted through one case study, and the mechanical responses such as road surface deflection, horizontal tensile strain at the bottom of asphalt mixture layers, and vertical compressive strain at the top of soil foundation were compared. The results demonstrate both programs provide reliable simulations, with good agreement observed in asphalt pavement analysis of nonuniform contact stress in asphalt pavement structures. Both offer efficient and practical solutions for the specified problems. [ABSTRACT FROM AUTHOR]
Abstract (Chinese):	轮胎与沥青路面结构之间的接触应力呈现显著的非均匀分布特征, 借助数值模拟方法方可高效求解非均布接触应力作用下沥青路面结构力学响应。文中选取 2 款计算机程序————基于三维有限元法的 Everstress FE 与基于三维连续有限层法的 3 D -Move Analysis, 剖析用于非均布接触应力数值模拟时二者的宏观原理、特点与差异, 结合某具体算例, 对比路表弯沉、沥青混合料层层底水平拉应变和土基顶面竖向压应变等力学响应。结果表明, 2 款程序在沥青路面结构非均布接触应力数值模拟中均具有较高的可靠性, 二者计算结果吻合度较好, 可实现方便高效地计算。 [ABSTRACT FROM AUTHOR]
