摘　　要：根据层合板理论,将路面视为Winkler粘弹性地基上宽度为B的无限长厚板,研究了交通荷载下混凝土路面的动力响应,也同时考虑运动荷载速度的影响.运用Fourier级数和Fourier变换技术得到了运动荷载作用下路面动力响应积分形式的解答,并利用数值Fourier逆变换得到运动荷载响应的计算结果,分析了荷载速度对位移和弯矩响应的影响.The dynamic response of reinforced concrete pavement,due to a moving load on the surface of the pavement,is investigated using the Fourier series and Fourier transformation technique.The pavement rested on Winkler viscoelastic foundation is treated as laminated slab with a width of B and infinite value in length.The dynamic response solutions of the pavement under a moving load are derived,and the integral.Numerical results are obtained using the inverse Fourier transformation.The results are consequently used to analyze the influence of load velocity on the displacement and bending moment.
