层间结合状态对复合混凝土路面力学响应的影响
Study on the Influence of Interlayer Bonding State on Mechanical Response of Composite Concrete Pavement
摘要
Abstract
To elucidate the mechanical response characteristics of composite concrete pavements under interlayer bonding conditions,a three-dimensional finite element model was established to systematically investigate the influence of various parameters,such as load position,structural composition,interlayer friction coefficient,and surface layer thickness on stresses at the bottom layer.The results show that the mid-region of longitudinal joints is the most critical position for load application.When the interlayer friction coefficient increases from 0 to 20,load-induced stresses at the bottom layer significantly decreases across all conditions,with a notable reduction in stress along the traffic direction.The C50+C40 composite structure demonstrates optimal mechanical performance,and changes in the strength of the lower layer have a more significant impact on stress distribution than those in the upper layer.Based on the combined effects of traffic and thermal stresses,this study proposes composite cement concrete pavement designs for various traffic load levels.关键词
