摘　　要：针对移动载荷下E地基上刚性道面水泥混凝土加铺层系统建立了力学模型，采用三维Fourier积分变换及反应换求得到解析解，采用数值积分求得了数值解，为加铺层系统的动态设计及评估 提供了理论基础。A mechanics model is constructed in the paper for the concrete overlay system of rigid pavements under moving load on E foundation.Exact solutions are derived from using 2D Fourier transform and inverse transform;Numeric solutions are derived from using numeric integration.This papar provides a theory basis for dynamic design and evaluation of overlay system.
