| 摘 要： | 将连续配筋混凝土路面视为粘弹性地基上正交各向异性板，运用三角级数和积分变换方法，对路面受局部冲击荷载作用时的动力响应做了分析，得到了路面的挠度、内力和应力的解析解，进行了数值计算分析，并和不考虑地基粘性时的静力、动力响应做了比较。最后，讨论了荷载冲击周期及地基粘性对动态响应的影响。

| Abstract: | Continuously reinforced concrete pavement is treated as orthotropic plate on viscoelastic foundation. Dynamic responses of the pavement under transient load are studied using triangular series and integral transformation. Analytic solutions for displacements, internal forces and stresses are obtained. Numerical results are given and compared with the responses of pavement under static and transient load on non-viscosity foundation. The effects of transient load period and foundation viscosity on the responses are discussed. |
