摘要: 本文建立了柔性路面结构的层状半空间粘弹性力学分析模型,并从基本方程出发,在频域推导了在动荷载作用下的路表位移响应解析表达式。通过与相关文献计算结果的对比,对方法的有效性及正确性进行了验证。数值计算表明,利用本文方法求解路表的动态响应具有简单方便、精度较高的优点。Abstract: A multilayered halfspace viscoelastic model for flexible pavement is developed. Based on the fundamental equations, an analytical expression of the surface displacement response duo to a dynamic load is derived in the frequency domain. Numerical results show that the present method is simple and efficient.
