| 摘 要： | 采用宽度为B的无限长正交各向异性薄板来模拟沥青路面结构,研究粘弹性Winkler地基上沥青路面的移动荷载响应,使得分析模型更接近于沥青路面实际情况.将轮胎与路面接触面积简化为矩形区域,运用三角级数和Fourier变换,在变换域中得到矩形运动荷载作用下路面的动力响应解答.并运用Fourier逆变换分析了荷载速度、地基阻尼路面竖向位移的影响,最后采用叠加原理分析了双荷载作用下路面的竖向位移响应.

| Abstract: | In this paper,the asphalt pavement rested on Winkler viscoelastic foundation is treated as orthotropic thin slab with a width of B and infinite value in length,and the interface area of tire and pavement is simplified as a rectangle region.The triangular series and Fourier transformation are adopted to analyze the response,and the solution of vertical displacement under a rectangle harmonic moving load is derived.Numerical results are obtained using the inverse Fourier transformation and are used to analyze... |
