| 摘 要： | 以一种更符合道面实际的力学计算模型——移动荷载作用下粘弹性地基上无限大弹性薄板系统来研究机场刚性道面弯沉的求解,应用线性系统的叠加原理和坐标变换,建立求解系统的动力响应广义积分公式,把运动荷载问题转化为获取位移脉冲响应函数。在柱坐标中利用拉普拉斯和汉克尔变换求解板在瞬时点源荷载作用下的解,再结合广义积分得到道面板在移动荷载作用下的弯沉解析解

| Abstract: | This paper is absorbed in the research of the analytic solution about airport rigid pavements,which is on semi-inlinite- viscoelastic foundation to moving load.Based on the transform of coordinate and principle of superposition,a generalized integral formula dealing with moving load problem is ostablished.An impulse response function used in the integral is obtained by means of Laplace and Hankel transform.The analytic solution to the moving load problem of plate is evalu- ated by converting variables. |
