摘　　要：本研究基于水泥混凝土路面结构建立力学计算模型,对水泥混凝土路面在使用阶段及早期收缩变形阶段的力学响应进行计算和分析。研究结果表明:层间作用对混凝土路面在使用阶段影响不大;层间作用对面层早期收缩变形的限制是导致面板底部出现裂纹的主要原因,水泥混凝土路面设计时应保证层间光滑接触。This study establishes a mechanical calculation model based on the structure of cement concrete pavement, and calculates and analyzes the mechanical response of the cement concrete pavement in the use stage and the early shrinkage deformation stage. The results show that the interlayer interaction has little influence to the concrete pavement in the use stage. The limitation of the interlayer interaction on the early shrinkage deformation of the surface layer is the main reason for the crack at the bottom of the surface layer. Smooth interlayer contact should be ensured in the design of cementconcretepavement.
