水泥路面沥青加罩不同计算参数的有限元分析

The analysis of stress response of asphalt overlays structure on cement concrete pavement caused by the change of

针对传统的多层弹性体系理论的路面力学计算方法难以全面分析水泥路面沥青加罩结构的荷载作用效应的问题 ,采用三维有限元计算模型 ,分析了水泥混凝土路面上不同加罩形式以及各自不同的结构计算参数 ,在临界荷位作用下的力学反应 ,得出了一些很有意义结论 ,对实际工程应用中合理选取加罩方案有一定的指导作用 .

The three dimensional finite element method was used to analyze the mechanics response of different asphalt overlays structure on cement concrete pavement with different mechanics calculation parameters under vehicle load. Some results were obtained and could be a guide to selecting the pavement structure and the material parameters.
