摘要
为探求非均布动荷载作用下粘/线弹性沥青路面模型之间的动态响应差别,结合我国当前半刚性基层路面特点,采用层状体系理论,建立ANSYS 3-D有限元模型,施加非均布动荷载,进行非线性求解计算,并对路面结构模型各层的动态力学响应进行比较分析和研究.
To study the difference of dynamic response between the linear elastic and visco-elastic road model, a 3-D FEA model of semi-rigid base asphalt pavement road was established on the layered the- ory with ANSYS software ,and non-uniform distributed dynamic load was loaded on the two kinds of road models. By nonlinear calculating, the dynamic response in the different layers of two kinds of road models were analyzed and studied.
