摘　　要：为了探究半柔性路面的力学响应规律,采用ANSYS模拟在不同面层厚度和模量、基层模量下,对路面结构模型进行力学数值分析。结果表明,增加面层模量可降低面层剪应变和增强路面抗剪性能;面层厚度需适当控制,否则反而使面层剪应力增加;增加基层模量会提高面层层底拉应力。In order to explore the mechanical response of semi-flexible pavement,a pavement model was established by ANSYS,and the mechanical analysis of the pavement was carried out under different surface course thickness,surface modulus and base modulus.The results show that the increase of the surface modulus can reduce the shear strain and enhance the shear resistance of the pavement,the surface course thickness should be properly controlled,otherwise,the shear stress of the surface course is increased,the increase of base modulus will lead to increase the bottom tensile stress of the surface course.
